Mariah Carey puckered up to her husband Nick Cannon at the 2012 TeenNick HALO Awards at the Hollywood Palladium last night. The pop diva was in the house to support her man along with his mother, a dapper Swizz Beatz, and Ne-Yo, who hit the stage for a performance. The HALO Awards (Helping and Leading Others) recognize teens who make a difference in their communities. The show will air Monday at 8 p.m. on Nick@Nite.
