Additionally, KSI has made multiple videos for the sporting company Rule 'Em Sports, where he'd take part in various challenges and activities with other YouTubers and celebrities.

KSI Army

The KSI Army is the generic name for the fans of KSI. This name was popular during KSI's peak in popularity from 2009 to 2011 but has significantly decreased in usage in recent years. However, fans still hold the hope that JJ will continue to use this name for his fans.

Music Career

KSI branched out into "rapping" around the same time the Sidemen formed.

No Sleep

KSI featured on a single by British rapper Sway, titled No Sleep. The song reached number 44 on the UK Singles Chart. The music video for No Sleep was released on KSI's YouTube channel on 20 October 2013.


On 23 March 2015, KSI released his debut single Lamborghini, which features British rapper P Money. The song reached number 30 on the UK Singles Chart, making it his highest charting single to date.

Keep UP (EP)

Later on in 2015, KSI revealed that he was preparing to release his debut EP. The lead single Keep Up was released on 13 November 2015 and features British rapper JME. The song was originally scheduled to be released on 1 January 2016, but was brought forward due to the song's appearance on Now That's What I Call Music! 92. Keep Up peaked at number 45 on the UK Singles Chart. On 8 January 2016, KSI released his debut EP titled Keep Up. The EP reached number 13 on the UK Albums Chart.

In early 2016, KSI announced that he would be releasing his second EP, due to be released towards the end of 2016. The lead single Goes Off which features British-Ghanaian musician Mista Silva was released on 29 April 2016. However, the single failed to make an impact on the UK Singles Chart.

Friends With Benefits

KSI released the EP's next single Friends With Benefits on 29 July 2016. The song features Dutch musicians MNDM and peaked at number 69 on the UK Singles Chart.

Jump Around

A new single titled Jump Around was released on 16 September 2016. The song features American rapper Waka Flocka Flame and samples the song Jump Around by House Of Pain.

Television and Media

In his YouTube career, KSI has faced controversy of matters such as sexual harassment, when he motor-boated Brandy Brewer at EuroGamer, and his 'rape face' which he has addressed and regrets doing. Due to these matters, he faced quite a lot of backlash and was ousted from certain events.

After becoming a particularly iconic figure in the British media industry, KSI has been invited to appear on numerous television shows, most recently on the comedy series 'Backchat', hosted by comedian Jack Whitehall. This special was broadcast on BBC Two on Boxing Day 2015.

In addition to television appearances, KSI has started to break through into the "comedic" interviewing of movie stars, including: Matt Damonand Ryan Reynolds.

A film titled Laid in America was premiered on 26 September 2016. The film starred KSI and fellow YouTube personality Caspar Lee. The film is about two foreign exchange students in America who, on their last day in the country, go on a bizarre quest to lose their virginity. However, this became the most pirated movie of 2016, meaning it is unlikely there would be any film in the future.

KSI currently hosts a series broadcast on his YouTube channel titled Pass the Pad, in which he plays computer games with celebrities including: Tinie Tempah, Jamie Oliver and Rio Ferdinand.

Disillusionment with Fame

KSI had not uploaded a video to either of his channels in February - June 2017, and he has also blacked out all profile pictures and banners across all his YouTube and social media accounts. He additionally took down videos worth over two billion views and deleted all of his Instagram posts except for one. This began to worry many of his fans, with some thinking he'd be diagnosed with a terminal illness or was suffering from depression.

KSI followed this up with a series of since-deleted tweets where he explained that he had come to dislike his fame and the special privileges he knows he gets on the grounds of being a "celebrity" - even though everyone is all treated equally - and stated that he would no longer like to be called a celebrity and wants to become a more "normal person". He also tweeted a quote by Charles Darwin that says: "We stopped looking for monsters under our bed when we realized that they were inside us.".

In an interview with DramaAlert, KSI said he did all of this so he could "evaluate himself as a person" and stated that he that he "doesn't care about the fame or money" and that he wants to "cleanse himself" as a human. KSI had been completely inactive on all his social media until he uploaded a photo on Instagram on 6 May 2017 saying "Growth".

He has been seen featured in the other Sidemen's videos, such as miniminter and Behzinga. He took part in the 2017 charity football match.

After his return, in Josh's Homegrown Podcast, JJ stated that he was tired of all the controversy and restrictions that come with the life of a YouTuber. JJ said he didn't like the state of the website and how people no longer made videos for fun. He traveled around the world when he was off the internet and claimed that he was "trying to evolve". Eventually, he explained how he no longer wanted to feel so "trapped" and would focus more on the reason he wanted to do YouTube in the first place, which was to enjoy making content.

Space EP

On 23 June 2017, KSI posted a new video, entitled "It's been a while...", implying that his return to YouTube is imminent. Alongside posting that video, he also tweeted out about an upcoming EP, called Space. It will be released on 30 June 2017.

Four days later (27 June 2017), KSI posted another video, his music video for the song Creature. It's the only song that has been released from the Space EP so far. It was previewed in the "It's been a while..." video, as the song appears to be heard in the background of the video.

The description of the video states "for Alfie". Alfie is a fan of KSI and ComedyShortsGamer who is living with bone cancer. KSI and his brother visited Alfie prior to the release of the song (and gave him a shirt). It is thought that the video is dedicated to him.

Sidemen War

On 3 August 2017, KSI tweeted out that he is leaving the Sidemen House, as well leaving the Sidemen group itself. This triggered a series of events known as the |Sidemen War.

Behzinga V KSI

On 6 August 2017, KSI "officially" left Sidemen, with his new video that he recorded in his new roommates' house titled: I'm Leaving The Sidemen. In the video, KSI explains that the reason behind his choice to leave Sidemen was Ethan. At the end of the video, KSI stated that he is making a "diss track" on the Sidemen.

On the same day, Josh and Ethan made two new videos. In Josh's video, he (jokingly) revealed that he was moving in JJ's old room. In Ethan's video, he jokingly revealed that he was moving in Josh's old room in the Sidemen House. Ethan's video also showed that he wrote "FU*K KSI!" on JJ's lamp.

New Girlfriend

ComedyShortsGamer made a video in which he "reviews" KSI's girlfriend. He claimed it was Jean Watts, an American musician and Instagram-famous persona. Eventually, KSI had an interview with Caspar, saying that we never will find her identity, and that she is from England and is younger than him (confirming that Jean is not his girlfriend).

Seana Cuthbert

KSI had a well-publicised relationship with Seana Cuthbert, and the two made several videos together. They split in mid-2014 after being together for around two years. He revealed the news in a video entitled "Googling Myself" released on 4 September 2014. KSI remains adamant that they are still "close friends" and that she's one of the "coolest" girls he has ever met. The rest of The Sidemen often joke about his break up with Seana in their videos.


KSI is also known for beefing with famous YouTuber Felix "PewDiePie" Kjellberg around mid-2016 in the midst of the site's infamous "drama" craze. KSI initially grew bad blood towards Kjellberg since he was one of several big YouTubers who criticised the craze as changing the YouTube community for the worse and creating an aggressive atmosphere between other YouTubers. KSI came out against this stance, calling PewDiePie and co. hypocrites because they've released monetized videos about drama.

Additionally, KSI was wronged by Kjellberg when he accused him of copyright-striking a video of his since it used one of his songs. This led to a series of rant-ish tweets from KSI where he stated that his music label, not him, filed the strike, and that Kjellberg was attempting to make KSI look bad. The two continually fired shots at one another through Twitter. One such tweet involved KSI claiming that Kjellberg's girlfriend, Marzia Bisognin, would break up with him and get with KSI.

The beef was somewhat revived when KSI teamed up with RiceGum in a feud against Kjellberg, with himself and RiceGum reportedly working on a "diss track" together against him (one that currently has yet to be released). Despite this, KSI came to Kjellberg's defense during the infamous fallout of the media portraying him as an anti-Semite and Nazi as a result of some "offensive" jokes he made, stating that he sympathized with Kjellberg since he knows what it's like to be in that spot. This is a view shared by many others, and seemingly a sign that the two are on the road to squashing their beef (if they have not done so already).

  • KSI owns a Lamborghini Aventador and a Porsche Cayenne (which is allegedly more of a "practical car").

  • KSI was the online face of Sport Relief in 2014.
  • In his Googling Myself video, KSI revealed that he is agnostic (neither believing in nor disproving the existence of a god).
