You knew Wiz Khalifa could scrap in MMA ... but did you know he could box too???
It's true ... at least, now it is -- after the rapper got a private, 1-on-1 fighting lesson from Evander Holyfield!!!
The Real Deal and Wiz hit up Jay Glazer's Unbreakable Performance Center in L.A. recently ... and the "Black and Yellow" spitter got in a dope training sesh with the champ.
Evander gave him some pointers on his defense ... Wiz explained how he's put some weight on his skinny frame -- and Glazer was there to document it all.
So ... why were the two hittin' the mitts together in the first place??
Wiz has a song dedicated to the boxing legend called "Holyfield" -- so, seems only right Evander gave him some fighting pointers in return.
Wiz has told TMZ Sports in the past he'd take -- and maybe even WIN -- a pro-MMA fight if the money was right ... but the question now is -- would he do the same for boxing?!?
Stay tuned ...
