YouTuber and boxer Jake Paul‘s feud with UFC boss Dana White will be continuing into the New Year, it seems.

In a tweet posted Saturday, Paul said he would, “retire from boxing and immediately fight Jorge Masvidal in the UFC,” if White followed his attached demands which included requests related to UFC fighter pay and welfare you can read in full below:

White responded in a video posted on Saturday evening. White began the video by refuting Paul’s assertion that he does cocaine on a YouTube interview, and said, “I believe that you’re a cheater, and I believe that you use steroids.”

White challenged Paul to submit to a steroid test and claimed that he would be willing to test himself for cocaine before going on to discuss Paul’s tweet.

In regards to Paul’s challenge, White said that Paul was “too stupid,” to really have written the demands. He continued, “If you two think that you can do it better than we do … you can treat the fighters better than we do, knock yourself out. Go start your own business.”

White also claimed that Paul’s current manager used to be an accountant for him, and called him a “scumbag.”

White ended the video by saying Paul’s career is “tanking,” and that he was only calling out UFC fighters like Jorge Masvidal “because he’s a pay-per-view superstar … You can’t sell pay-per-views.”

You can watch White’s full video below:

Paul already clapped back to this video with his own video, filmed at a beach party in St. Barths where he dismissed the steroid use claims and referred to himself as a “fat bitch.”

Paul is 5-0 In his boxing career after knocking out former UFC champion Tyron Woodley last month in a rematch.
