Lil Pump is picking a side ahead of the big Jake Paul and Mike Tyson fight ... telling TMZ Sports he thinks the Problem Child is gonna beat the boxing legend!!
"I feel like Jake is just faster, he's younger," Pump said of the July 20 event while at LAX. "Obviously, Mike's got experience, but Jake's gonna do what Jake's gonna do. It's gonna be a very interesting fight ... but Jake got this one."
SORRY BRO
The "Gucci Gang" rapper knows firsthand what the 27-year-old former Disney star is capable of -- after all, he took a vicious liver shot after recording an episode of the "BS w/ Jake Paul" podcast earlier this month.
