KSI shows off his incredible eight-month body transformation after cutting HUGE amount of weight for Swarmz fight

KSI has undergone a dramatic body transformation ahead of his long-awaited return to the ring.

The YouTuber and music star will be back in action on August 27 against fellow social media star Swarmz and Mexican pro boxer Luis Alcaraz Pineda in a double bill main event.

KSI was due to face fellow long-time rival Alex Wassabi, who beat his brother Deji in a boxing match earlier this year.

However, Wassabi was forced to pull out through injury.

KSI's clashes with Swarmz and Pineda will be his first outings since his controversial split-decision victory over Logan Paul in November 2019.

KSI let his diet slip after winning the Los Angeles showdown and piled on the pounds - although he's shifted the blubber in a drastic body transformation.

The 27-year-old shared a video documenting his eight-month journey back to fighting fitness on his social media channels on Friday morning.

At the star of the clip, a podgy-looking KSI - real name Olajide Olatunji - stood in front of the camera and turned around to show off his whole body.

But seconds later, the video cut to a lean and mean-looking KSI showing off his shredded abs.

His accompanying caption for the video read: "TikTok age restricted my video because it thought my chest were actual t**s.

Another said: "This is insane."

And another said: "This is so mad."

One chimed in: "This body transformation is f***ing mad, fair play."
