Jake Paul punched a YouTuber so hard in the gut, he made him sh*t himself and the footage is hilarious.
'The Problem Child' is gearing up for his seventh professional bout as he takes on fellow unbeaten fighter Tommy Fury on February 26 in Saudi Arabia.
Despite finally taking on a genuine boxer, the 26-year-old appears to be having fun in training as evident by Preston Lopez's clip of him at his gym.
Preston travelled to Puerto Rico where Paul has based himself ahead of his Middle East showdown against Fury.
And he took a body shot from the 6-0 fighter and, it's fair to say, it didn't go down well.
Paul, wearing a boxing glove on his right hand, landed a body shot on Preston, who collapsed to the canvas in agony.
Upon returning to his feet, he revealed that he had 'pooped' himself, saying: "Oh, dude! I pooped a little bit!" He continued: "It feels a little wet."
Paul clearly packs a punch having knocked out the likes of Ben Askren and Tyron Woodley in his career.
And Preston can probably vouch for how hard the YouTuber-turned-boxer hits based on his latest upload.
Paul will be hoping for another knockout victory when he takes on Fury in a few weeks.
He's super-confident of beating the British fighter and even gave 12 crazy reasons why he 'cannot be defeated'.
On Instagram, he said: "I'm more athletic, have more heart, more of a WHY, more poised, more emotionally intelligent, more spiritually connected, more calculated, more willing to die, more patient, more studied, more willing to learn, more supported and loved than any of my opponents.
"So in this lifetime I just simply cannot be defeated. For this timeline I am extremely grateful."
Paul is also ramping up the trash talk as he aimed a brutal dig at Fury, who recently became a dad.
Who wins? Let us know.
