The Voice coach Adam Levine makes his acting debut in the highly anticipated romantic comedy Begin Again, but it's actually his co-stars Keira Knightley and Mark Ruffalo who were intimidated by People magazine's reigning "Sexiest Man Alive."
"All I'm gonna say is I'm happy that I don't have any scenes with Adam Levine in this movie," Mark admitted to ET's Rocsi Diaz at the film's New York City premiere Wednesday. "He's intimidating. Are you kidding me? He's a superstar."
