KSI has displayed his ripped physique ahead of his return in boxing.
Olajide Olayinka Olatunji, a YouTube star, beat Logan Paul in a scrappy split decision win in 2019.
He remained focused on his fledgling music career, which had ruled out a return to the ring.
KSI, however, has announced that he is currently in training to make his return to boxing on August 27.
It happened during the performance of the celebrity fighter at Wembley Stadium's Summertime Ball.
He did it topless, showing off his toned body and looking remarkably fit.

KSI, 28 years old, was the first to box in a white collar fight against Joe Weller (26), winning in round three with a TKO.
He also drew in the same year against Paul, his 27-year-old business partner, in Manchester. Their rematch was set up a year later.
However, it was controversially decided that the fight would be a professional one with Anthony Joshua's promoter Eddie Hearn staging it.
It was again a six-round affair with KSI recovering after a knockdown to beat Paul. Paul had a two point deduction.
SIGN UP DEALS AND FREE BETS - THE BEST NEW CUSTOMER OFFERINGSKSI was trained by Viddal Riley (6-0 cruiserweight prospect), for his three boxing bouts so far.
Riley, however, is now focusing on his own professional development with KSI and not moving to a different gym.
It was a secret switch up until now, but Leon Wills, his strength and conditioning coach, has made it public.
Alexis Demetriades is coaching KSI at the London Shootfighters gym.
Fred Talks Fighting was told by Wills that Wills is training with Alexis as part of Shootfighters gym.
"But yeah, KSI looks sharp, watched him spar on the other day. Very good, very fit. He performed well when I saw him."
