Justin Bieber was the big winner at the 40th anniversary American Music Awards on Sunday. Not only did the teen idol share the stage with Nicki Minaj, he also went home with three awards including Artist of the Year. He brought up his mother and thanked Usher during his acceptance speech.

His “Beauty and a Beat” collaborator Nicki scored two trophies including Favorite Rap/Hip-Hop Artist and Favorite Rap/Hip-Hop Album for Pink Friday: Roman Reloaded.

She dedicated the awards to her Barbz. “I love you so much, you are so passionate and so inspiring,” said a grateful Nicki. “Thank you so much for voting your little tiny fingers off. I could just eat you and kiss you and love you and hug you.”

Other winners included Beyoncé (Favorite Soul/R&B Female Artist), Rihanna (Favorite Soul/R&B Album), and Usher (Favorite Soul/R&B Male Artist). See the full list of winners below.
