LOS ANGELES, CA - Justin Bieber may have just broken up with Selena Gomez, but one thing's for sure, the teen pop star is definitely not hurting for attention.
McCarthy was presenting Bieber with the award for Favorite Pop/Rock album when she grabbed the 18-year-old from behind and planted a smooch on his neck.
According to McCarthy, she was just having a little fun with Biebs referring to herself as a "cougar" after the event.
The American Music Awards aired live from Los Angeles on ABC Sunday, November 18.
