19. LL Cool J
Twenty-five years since he first rocked the bells, Uncle LL is still handsome, still ripped, can still sling verses harder than MCs half his age (he’s 43, in case you were wondering). And to top it off, he’s matured into terrific actor, trading zingers and tough-guy swagger with Chris O’Donnell on “NCIS: Los Angeles.” Yep, the ladies still love him. Good thing, because "Cool J" just doesn't have the same ring to it.
