Justin Bieber was the big winner last night at the 40th annual American Music Awards picking up the top award for Artist of the Year.

The singer brought his mother on stage to help him pick up the honour and he thanked her saying "I wanted to thank you for always believing in me." He added that it is "hard growing up with everyone watching me."

The teenager also won favourite pop/rock album for Believe, and male artist. Picking up the nod for best male artist Bieber had a go at his detractors saying "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."
