Mario Sexy

When you can sing, act, and have a set of abs like that, you only need one name.  Mario!  This Grammy Award nominee and Billboard Award-winning singer, songwriter, and actor have been pumping out hits since his 2002 self-titled album.  He's also acted in 2006's Step Up, opposite Channing Tatum, as well as 2007's Freedom Writers.  You can catch him most recently as a series regular on Fox's Empire, where he gets hot and heavy in a recording studio session and records his new hit song in the buff.  Inspiration strikes him when he's got nothing to hold him back, including clothes.
