Jake Paul knocked out AnEsonGib within one round before calling out rival KSI on Thursday night in Miami.
The American floored his UK YouTuber foe three times in the opener, causing the referee to stop the mismatch.
Few predicted just how one-sided the bout would turn out to be, with Gib having previously won his two white collar bouts.
However he was simply blown away by Paul in three painful minutes.
Jake immediately ran over to the edge of the ring to call out KSI in the aftermath of the result, with the Brit (who recently defeated his brother Logan) looking dejected having just seen his friend beaten.
The pair then got into a heated face-off during the post-fight interviews.
Paul said: “I caught the boxing bug, I put the work in and I’m in love with this sport.
“My power, my speed took him out in one round.
“I dedicated the past five months of my life to this up in Big Bear with Shane Mosley.
“I didn’t even get to showcase my boxing ability, it was all just natural instinct.
“We started visualising the first-round knockout and it happened.
“KSI is next. Where’s that p***y at.”
