Justin Bieber Squirms During Jenny McCarthy Kiss Attack: AMA VIDEO

justin bieber thanks haters

Justin Bieber had a big night at the 2012 American Music Awards, winning Artist of the Year, Favorite Pop/Rock Male Artist of the Year and Favorite Pop/Rock Album for 'Believe.'

Sunday's events were memorable for a number of reasons:  his harem pants, a series of ambush neck kisses by Playboy hottie Jenny McCarthy and the fact that his date was his mother Pattie Mallette instead of his off-again girlfriend Selena Gomez.

Taking home the first award of the evening, Bieber surprised some viewers with the decidedly negative tone of his acceptance speech.

He said, "Thank you, thank you.  First of all I'd like to say ... this is for all the haters who thought that maybe I was just here for one or two years.  I feel like I'm going to be here for a very long time."

He went on to thank his mom, "She's amazing, she's beautiful."

Check out his 'hater-inspired speech' and the kissing ambush below.  Note: JB looks like he'd sooner die than continue to submit to the affections of Jenny M:
