JUSTIN Bieber has been hanging out with scantily clad models at a Victoria’s Secret fashion show.

The Baby singer performed at the event with Rihanna and Bruno Mars, and got air kisses backstage from models in skimpy silk dresses.

Justin - whose romance with Selena Gomez is rumoured to be on the rocks - joked on Twitter: “Tough life @brunomars. #VSFashionShow.”

He added later: “Great Show!! Thanks for having me @victoriassecret ! #VSFashionShow.”

Rihanna also had fun on stage at the event in New York. The Rude Boy star tweeted pictures of herself on the runway in a lacy pink outfit and said: “I’m a #VS girl now lol.”
