Justin Bieber brought his mom on stage to accept his award at the American Musica Awards. INSIDE EDITION has the behind-the-scenes scoop.

It was a big night for Justin Bieber at the American Music Awards. The pop star took home three awards, and got a bunch of kisses from actress Jenny McCarthy.  

“Wow, I feel violated right now,” he said laughing.

Backstage, McCarthy spoke about her Bieber obsession.

“It was fun, I hope it was worth it for Bieber. I did grab his butt, i'm single,” she joked.

Bieber shocked his mom, Pattie, by pulling her on stage with him to accept the biggest prize of the night -- Artist of the Year.  

“This is my mom.  She's little, but she's beautiful. I wanna thank you for always believing in me,” he said.

The pop star had a message for his detractors, “This is for all the haters who thought that I was just here for one or two years. I feel like I’m going to be here for a very long time."

Christina Aguilera showed off her curves, performing in a black leotard.

On the red carpet, high fashion was all about high hemlines.

“I'm really, really happy right now,” said Taylor Swift.

Before accepting her award for favorite country female, Swift hit the red carpet in a short beaded number.

George Clooney’s girlfriend, Stacy Keibler, showed off her 42-inch long legs wearing an embellished mini dress.

Supermodel Heidi Klum stepped out in a teeny gold dress with a thigh-high slit.    

INSIDIE EDITION spotted Korean sensation, PSY, rushing in before his big performance.

“You gonna see very special thing tonight, trust me," he said.

Sure enough, PSY joined MC Hammer and performed a mash-up of a Hammer classic and “Gangnam Style."

It was the nights showstopper!
