Bruno Mars - very underrated in my opinion! Super, highly talented dude. Maybe his Superbowl performance will make new fans!

Bruno Mars - He's too young, of course, but the 19 year old me woulda been all ova that. Brother can dress himself, he's mad talented, and he's cute enough to be a girl. In fact, were he a girl, I would still do him.
