Wiz Khalifa Gets Boxing Lesson From Evander Holyfield, Real Deal Punches!

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 ...
