Hard to believe this singing hunk started out as member of the R&B kid trio Immature, a group that hit the pop charts and the big screen (House Party 3 and 4) in the early ’90s. After going solo in 2003, Houston released five studio albums, including 2005’s Naked and 2009’s Mr. Houston. As an actor, he’s been in films like Fat Albert and the dance classic You Got Served. He also played a role on TV’s Sister, Sister. Unfortunately in 2010 Houston was embroiled in a controversial and very public exchange with former B2K member Raz B.
