Olajide Olatunji (born 19 June 1993), better known as JJ or "KSI", is a African/British YouTuber mainly known for game-play videos and comedic sketches.
KSI was born and raised in England and, when first starting YouTube, lived with his parents in London alongside his brother, Deji (a.k.a ComedyShortsGamer). KSI 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.
KSI's overconfident personality means he sticks out in the FIFA YouTube community; and the humour in his videos often show the FIFA community's frustrations at EA and the FIFA games themselves.
He used to date vlogger 'Seanyxxx' (better known as Seana) but broke up with her in 2014. The two still remain close friends.
Since his sudden growth in popularity throughout 2013, JJ helped form a group called the Ultimate Sidemen alongside some of his closest friends. Initially, the group consisted of six relatively famous British YouTubers (miniminter, Vikkstar123, Behzinga, Zerkaa and TBJZL) but with the addition of Wroetoshaw in early 2014, became seven.
In February 2014, JJ and three other Sidemen members bought a house together in London. They commmnly refer to it as the 'Sidemen House'.
However, in late-2014, JJ bought a large and expensive penthouse in North London. It is thought that he now alternates between living in the Sidemen House, and this apartment.
JJ was banned for life from the Eurogamer Expo in 2012 due to alleged sexual harassment. After the incident Microsoft cut all ties with JJ and he stated an apology. He did however, upload a video of the event but took it down for obvious reasons.
JJ has two YouTube channels. His main channel is called KSI which focuses on FIFA and vlogs and his other channel is called 'KSIOlajidebtHD', where he uploads other games (primarily GTA 5 and arcade computer games). JJ has not uploaded a video to his second channel in months, and it is unlikely that he ever will.
Being the second most popular British YouTuber (behind TheSyndicateProject), KSI has a vast array of contacts and commonly collaborates with many including:
