Wiz Khalifa is taking his MMA training really seriously.

So is Post Malone.

In fact, when asked about Wiz's aptitude in the octagon, Malone said he'd like to see Wiz square off against a UFC legend. 

"He looks like a tough mother fucker, man," Post said of Wiz. "I wanna see Wiz and Silva. They got the same type of body type, long and skinny."

Post did admit he wasn't sure Wiz could beat Silva.

Post is actually really good friends with Wiz, so this isn't necessarily a case of him trying to get Wiz killed.
