While it seems the rest of the world has forgiven Chris Brown for his fight with then-girlfriend Rihanna, Maroon 5 frontman Adam Levine isn’t quick to do so.

Maroon 5 lead singer Adam Levine appeared on Howard Stern radio show and was prodded with questions regarding “The Voice” co-judge Christina Aguilera’s weight gain.

Life can’t get any better for Maroon 5 frontman Adam Levine. He is a successful musician and one of four judges on “The Voice,” NBC’s hit talent reality show. But the “She Will Be Loved” star admits to having at least one regret. No stranger to tattoos, Levine said he owns a tattoo he’s not too proud of.
