KSI leaked a message he received from a model who was told to roast him in a Jake Paul music video.
KSI and Paul have been rivals for years now and have constantly gone back and forth. Despite the animosity between them and rumours, the two have never squared off in a boxing bout as mooted.
Though both have locked horns with Tommy Fury, it is Paul who has had the bigger fights and paydays - making a reported £68 million for his Netflix superfight with Anthony Joshua.
The Problem Child was brutally knocked out in the sixth round in Miami and suffered a broken jaw that means he will be eating liquids only for around a week.
KSI couldn't resist aiming a dig at Paul, brother of his business partner Logan, taking to X to write, "Congratulations AJ" with a picture of Paul's priceless face expression as he was walloped by the two-time heavyweight champion.
He teased him further on Instagram with additional pictures and in a second follow-up post on X, wrote: "Now I just need an Arsenal win and Andrew Tate to get knocked out and then this will be a fantastic weekend."

The commentary video amassed 16 million views and saw KSI appear astonished during the start of the song's video as one model asked Paul when he was fighting 'The Nightmare'.
He replied, "Whenever he stops playing FIFA". But more insults were to come as one girl claimed that KSI had attempted to DM her, with a model with a British accent adding, "Girl same but I heard it was like this [small]" - in a reference to his penis.
However, the joke wasn't quite on KSI as in his video, he proceeded to reveal a DM from the girl in question - who told him that she did not mean any offence by the scene as she claimed she was just "delivering my lines".

The message read: "Ok I've got a funny story here. The girl that was acting in this little scene actually DM'd me. Let me show you real quick.
"Dude, I was the girl with the 'British accent' in Jake Paul's music video 'roasting you' and I just want to say I was just delivering my lines. I don't even know if you're going to see this, but I was just doing a job and I hope you didn't take offense! Much love to both you and Jake!"
Commenting on the intro to the video, KSI added: "I don't know it's just funny innit'. So pretty much after that, this whole intro is dead now. We move. It's so funny when they're like, they heard my penis is like this [small] - it's just not though!"
KSI has not fought since his bout with Fury and a hand injury kept him on the sidelines for a considerable period.
Nakisa Bidarian, Paul's business partner at Most Valuable Promotions, has hinted that they could meet in a 2026 superfight at Madison Square Garden - though the latter's injury could delay proceedings.
