Wyclef Jean drove concertgoers at MTV Africa Music Awards insane when he stripped down to his underwear challenge fellow underwear-attired rapper Akon to a push-up contest on stage.

But crazed fans did not know that Wyclef spent much of his free-time seemingly prepping for the event, a favorite pastime for the singer/activist/friend of Brangelina.

Jean stayed with the rest of the MTV show participants at the luxury Tribe hotel in downtown Nairobi and spent time either recording in a make-shift studio he set up in his penthouse suite or challenging people -- anyone -- to a push-up contest.
