Justin Bieber To Perform 'Pray' At American Music Awards

'It's very uplifting, very motivational,' he tells Ryan Seacrest of his new song.

Justin Bieber is set to perform at the American Music Awards on Sunday, and the teen superstar has revealed he'll be playing his new song, "Pray."

"I don't know if it's out there ... I'm performing 'Pray,' " he told Ryan Seacrest on his radio show Wednesday (November 17). "It's a very uplifting song, very motivational. It definitely comes from the heart.

It's very beautiful. I definitely thought of Michael [Jackson's] 'Man in the Mirror' when I was writing it."

Bieber also talked about his new album, My Worlds Acoustic, out next week. On the show he teased a small portion of the acoustic version of "Favorite Girl." "I think that there's always going to be people that try to bring you down and you just got to prove them wrong," he said of the album. "I'm just blessed to have devoted fans. My fans just kind of spoil me."

The singer talked about his 2011 3-D flick, "Never Say Never," saying that "it really shows me." And he dished about a recent dinner outing with Rihanna.

"I don't know. We all went out for dinner, the label and everybody, and Rihanna was there," he recalled. "Me and her sat together. I said a couple lines to her. I was just being funny. I don't remember how it came up, but she was like, 'You have abs? Show 'em!' So I did, and she tweeted [about it]."

Bieber also talked to Seacrest about wanting to work again with Kanye West, who remixed his "Runaway Love" track. "For sure! He's a great guy," he explained. "He's really cool to work with and his music just speaks for itself. I heard his new album. It's incredible."
