Justin Bieber performed at the 2012 Annual Victoria’s Secret Fashion Show surrounded by the world's top lingerie models, and his girlfriend, Selena Gomez, was nowhere in sight.

According to CBS News, Bieber wore all white and performed "Beauty and a Beat” and "As Long as You Love Me.”

Bieber did not seem to miss Gomez too much, as MTV says he told reporters on the red carpet before the show, "It's like a dream come true. I would rather be here than anywhere in the world."

After the Victoria’s Secret show, which airs on Dec. 4, Bieber attended an after-party with models Miranda Kerr and Lily Aldridge, among others.

“He was sitting with a group of people … laughing and having fun with a couple of models,” an insider revealed to Hollywoodlife.

“Miranda Kerr was there, and [Bieber] was sitting right by Lily Aldridge and her Kings of Leon hubby [Caleb Followill]. It seemed more friendly then flirty. They were all having a great time hanging out, and they seemed so comfortable. He got up from the table at 12:15, so he was there for right under an hour.”

There could be trouble in paradise for Gomez and Bieber, as they have not been spotted together recently, and a source told RadarOnline that the 20-year-old actress and singer is only staying with him because he is "good for her brand."

“Dating Justin is good for Selena's brand. Together they're a brand!" the source explained. "Everyone in Selena's camp is aware of Justin's star power and is urging her to make it work with him."

"Let's just say that if for some reason Justin's star ever fell, Selena would drop him immediately," the source went on to say.
