Rihanna, Bruno Mars and Justin Bieber hit the stage at the 2012 Victoria's Secret Fashion Show to perform alongside the scantily clad models as they walked the runway.

While Rihanna and Bruno Mars focused on their sets, Rihanna singing 'Diamonds' strutting her own stuff in a tight fitting black dress and unusual white rimmed sunglasses and Bruno crooning his hits into a mic surrounded by a brass band, Bieber looked pretty distracted while performing his latest hit singles 'As Long as You Love Me' and 'Beauty and a Beat' when the models passed his way. Doutzen Kroes, Joan Smalls, Lily Donaldson, Sui He and Miranda Kerr were among the Victoria's Secret angels and while the show kicked off with a circus theme, it soon progressed to St. Patrick's Day, July 4th and even Halloween in a calendar girl style run rounding off with a glamorous flower theme.

As much as he tried to deny it, Justin's mind was really not on the job in hand at the hour long show and appeared to arose much speculation about his loyalty to his then girlfriend Selena Gomez. In pictures from the filming of the show, his mouth seemed to permanently hang open while he starred wide eyed at all the VS girls, but none more so than Barbara Palvin who he apparently went out to see The Lion King on Broadway with after the show which, according to her simple Twitter message of '.' next to a photo of the pair together with another friend, Selena wasn't too impressed by.
