TikTok star Bryce Hall has a truly adorable reason for wanting to beat the living hell out of YouTuber Austin McBroom in their upcoming boxing match ... saying if he comes out with a K.O., he's getting his mom a new house!!!
Of course, more Internet superstars are following Logan and Jake Paul's lead into the ring ... with 21-year-old Hall and McBroom, 28, headlining the "YouTubers vs. TikTokers" card on June 12.
Hall tells TMZ Sports he's SERIOUSLY cashing in on the event ... doubling down on his claim he's really going to make $5 million just to enter the ring.
On top of that, Hall -- who has 19.6 million followers on TikTok -- says he's going to get another $1 MILLION bonus if he's able to knock out the former college basketball player ... and that money would go to a great cause.
"That's like, my mom's house right there," Hall told us outside Toast in L.A. "I'm gonna buy my mom a house right after the fight. And, that knockout is my mom's house ... that's how much it means to me."
Hall shows us how serious he is by displaying some of his moves ... and even lets a random dude on the street punch him in the stomach!!
There's more -- we also talked to Bryce and his buddy Tayler Holder about Jake's fight against Ben Askren this weekend ... and they think it's gonna be a BAD night for the ex-UFC star.
