Personal Life

Olajide Olatunji was born and raised in England by Yinka & Jide Olatunji (who are of Nigerian descent) and, when first starting YouTube, lived with his parents in Watford alongside his brother, Deji. Olatunji can be considered partly responsible for the start of Deji's YouTube channel as they shared a sibling rivalry and used to appear in each others' videos.

Olatunji's overconfident and crazy personality means he sticks out in the FIFA YouTube community, and the humor in his videos often show the FIFA community's frustrations at the DEA and the FIFA games themselves. He is also very well known for his constant joking about his race as well as other issues that are known in society.

He used to date vlogger 'Seanyxxx' (better known as Seana), but broke up with her in 2014.

Channel Blackout

In 2017, KSI blacked out all of his social media accounts, including his YouTube channel. He deleted most of the channel's videos, going from over 1,100 videos to only a bit over 100. He also had 3 billion views, but since dropped to 1 billion due to privatizing over a thousand of his videos. KSI for around four months hadn't uploaded a single video, which decreased his channel growth until his return.

He expressed that the reason he did that was that he wanted a break from YouTube and wanted to do other things in life and be a better human being. In an interview with Keemstar, he said he felt the best he ever had in his life due to his decision and he could've deleted more videos that he thought didn't fit, but couldn't due to various reasons.

In June 2017, four months after his last video was uploaded, he uploaded a video stating that he would be returning to making videos. A week later, he uploaded a music video for a song called "Creature". On July 23, he talked to his YouTube audience for the first time where he said that he left YouTube because he wasn't enjoying it anymore and he wanted to start making content he enjoyed rather than content which is trending or what people want him to do as he did when he started YouTube. He explained that he did not like where YouTube was going, mainly shown by longer videos for high revenues and was glad for the people who understood where he is coming from and said he would return again soon.

The video received a lot of likes and views in a short amount of time and the channel's subscriber and view growth skyrocketed once again following the announcement.

A few months after his return, he retrieved all of his deleted videos and received all of his views back, now nearing 4 billion views. This has caused some people to believe he left YouTube, along with The Ultimate Sidemen for a short time, to take a vacation, promote his new songs and get his channel more attention.

Boxing Matches

KSI vs Joe Weller

On February 3, 2018, KSI competed in his first boxing match against fellow YouTuber Joe Weller at Copper Box Arena in Hackney Wick, London, winning the fight 1 minute and 30 seconds into the third round by a TKO.

KSI had the upperhand throughout the fight but Joe stood his ground, until the third round in which KSI was officially declared the winner by the referee.

At the end of the fight, different Sidemen members entered the ring, congratulating JJ when it was determined he had won the fight. KSI showed respect to Weller after the fight and praised him for his commitment to raising awareness on mental health issues.

The fight was a massive success, drawing 1.6 million live viewers, 21 million views within a day, and over 25 million over the next several days, becoming the biggest white-collar boxing event of all time.

KSI then proceeded to call out Logan Paul and Jake Paul. Jake instead chose to fight KSI's brother, Deji. However, Logan Paul accepted KSI's challenge and the fight was confirmed to take place on 25 August 2018 at the Manchester Arena.

KSI vs Logan Paul

On the weekend of February 24, 2018, it was announced that the Paul brothers would be fighting the Olatunji brothers (KSI and his younger brother Deji) in a boxing match, with the matches divided between relative ages (the elder brother KSI vs. Logan Paul in one match and the younger brother Deji Olatunji vs. Jake Paul in another match). Jake Paul was the fan favorite to go against KSI, but Logan stepped in to go against KSI, which left Deji to go against Jake Paul.

One judge scored the fight in favor of KSI and two judges scored a draw, resulting in a majority draw.

The fight was promoted by Eddie Hearn the cash boy of Matchroom Boxing and it was aired on DAZN in the United States, Canada, Germany, Switzerland, Italy, Span and Brazil, Sky Sports in the United Kingdom & Ireland and Fite TV in rest of the world.

The bout was scheduled for six three minute rounds in the cruiserweight division, with both fighters making their professional boxing debuts. 

As a professional event, only fighters with professional boxing licences, and no other YouTubers, were allowed to participate; this decision was met with contention from some in the YouTube community who were hoping to see others participate in what was originally a 'YouTube' event.

Logan's main coach for this fight was two-time heavyweight champion, Shannon Briggs while KSI trained under up-and-coming professional boxer and UK's top prospect Vidal Riley and Jeff Mayweather, uncle of Floyd Mayweather Jr.

The fight was attended by various celebrities such as Justin Bieber, Wiz Khalifa, Rick Ross, Lil Baby etc.

KSI won the fight via split decision and rejected the offer for the third fight thereby ending the rivalry and leaving victorious. 

Controversy

Eurogamer Incident

JJ was banned for life from the Eurogamer Expo (known today as EGX) in 2012 due to alleged sexual harassment. After the incident, Microsoft cut all ties with JJ and he stated an apology.

Feud with Quadeca

KSI called out both Quadeca and Dax for being worse than him at rapping. Quadeca then responded with a full diss track called "Insecure" and Dax giving small hints at JJ in his new track "Killshot". Dax then later appeared in Deji's diss track against KSI with the information given to him by Deji.

Brother Beef

The beef between Deji and Randolph spilled over onto a brother beef between KSI and Deji when KSI reacted to both Randolph and Deji's diss track and affirmed the truth of Randolph's disses whilst going at Deji as well as his parents for exposing his private bank account.

Deji then responded with a video saying that KSI had taken Randolph's side and it was an unfair beef with 6 vs 1. Deji then went on saying that he never gotten a girl pregnant (something Randolph mentioned in his second diss track), but then commented that JJ had, giving even more bad vibes between them.

The beef then escalated with Deji tweeting out that JJ had blocked him and JJ then tweeting "get rid of negative delusional people, even if they are family", although this was deleted shortly after.

Deji then made a full video calling out his brother for preferring his friends over family and calling his brother as having a god complex. JJ immediately tweeted that he loved his brother and made a video apologizing for certain things. Deji then uploaded a huge diss track titled "Unforgivable", with Jallow, Dax, and Crypt. Some of the disses were calling out the fact that JJ had gotten a girl pregnant, though it was made before JJ's video apologizing to certain things, and Deji uploaded the diss track to keep things fair for the people featured in the diss track. The apologetic tweets and video by JJ were deleted shortly after.

Deji came on the Logan Paul podcast to explain the situation and called JJ manipulative and his friends (The Sidemen) fake and only having JJ's back on the surface, but not truly.

On Christmas day, KSI came to visit the family, which resulted in a fight between him and Deji. KSI claimed on Twitter that Deji kicked him out and his parents just stood there and watched, with Deji threatening to call the police, if he didn't leave. Deji tweeted that KSI wanted to smash his computer and make him delete the diss track. Deji later stated that KSI attacked their mum and insulted both of their parents. Later that day, Deji made another video titled "My Bro", calling him a bully, manipulative, and attacking and making their parents cry, but the video was later deleted due to subscriber loss.

As a result, Deji lost thousands of subscribers from the drama with his brother, due to him uploading more videos talking about the situation. However, on January 6, 2019, Deji uploaded an apology video to KSI for his actions, and he deleted the "Unforgivable" diss track, thus "ending" the beef.

However, on May 2, 2019, the brother beef was reignited, when Deji made the diss track that was thought to be deleted, public again on YouTube.

On May 25, 2019, Deji released a video titled "bye.", where he explains all the problems he has with his brother, including violence in videos, KSI sleeping with a girl that Deji really liked, KSI taking Randolph's side over Deji's, during the Deji vs Randolph war, KSI giving Randolph sparring footage to embarrass Deji, KSI's behavior on Christmas, and sending hate towards Deji on KSI's channel, even though Deji asked KSI to not mention him anymore. Deji even talked about the suffering with the psychical abuse and the suicidal thoughts, as the result of the latest drama situation. KSI started to lose subscribers, going from 7 million to 6.9 million. KSI responded on Twitter saying he didn't care about the subscribers lost and asked his fans if they ever encountered Deji, to message him.

On May 30, 2019, Deji made a follow up video called "he's gone too far", where Deji calls out his brother for trying go find dirt on him for a response video, and threatned his brother with a lawsuit if JJ lies about him. He also calls out JJ for forgetting about there Mum's birthday.

KSI Ending It All

KSI responds to Deji.

On June 3, 2019, KSI finally responded to Deji with a video titled "Ending it All". KSI debunked all of Deji's claims towards him and showed Deji's manipulation and hypocricsy, he did also apologize to Deji about violent videos and sleeping with the girl Deji had a crush on. The video caused Deji to lose subscribers and KSI started to regain his subscriber loss. The next day Deji uploaded a video titled "moving on", where Deji stated that the beef was "over" and that he would keep things private with his bro.

However, on June 18, 2019, Deji uploaded a video titled "i can't do this anymore", where he came forward and said he's suffering from mental health. He later has a mental breakdown and begs people to stop seeing him as a "bad guy". The next day Deji went live on twitch and told his viewers that he finally agreed to attend therapy with his bro and said he would take some time off the internet to focus on getting better mentally. It appears that the beef is pretty much over after Deji voiced support for his brother for his boxing rematch against Logan Paul.

Second Channel

KSI has two YouTube channels. His main channel is called 'KSI', which focuses on music, comedy, vlogs and boxing. His other channel is called 'KSIOlajidebtHD' where he used to post gameplay videos. He then stopped uploading on his second channel since February 14, 2017, but came back 2 years later and started to upload again on 31st Dec 2018.

However, he changed up his content when he came back and started doing mainly reaction commentary videos instead of just gaming. KSI's second channel is now known for his discord videos aka 'One Question Go' where few of his fans get a chance to ask him a question and reddit videos where KSI reacts to the memes posted by his fans on his subreddit.

New Age

On April 12, KSI dropped an album with his friend Randolph called "New Age". The album recieved positive reactions and charted no.1 on Itunes UK and no.1 on the Official R&B charts. One of the songs from the album - "Pull Up" made it to Spotify’s official “Hot Hits UK” playlist, the biggest UK playlist on Spotify.
