Katy Perry made a surprise appearance to join hubby Russell Brand at the London premiere of his new flick, Arthur, last night.
The E.T. singer, who took time out from her California Dreams World Tour, looked stunning on the red carpet in a nude glittery gown, as she joined Brand at London's O2 Arena for the event.

It seemed that Russell was more than happy that his wife of six months was by his side, even cheekily grabbing Katy's bottom when posing for pictures with Perry.
The couple, who got hitched in India last October, even enjoyed a lingering smooch in front of the press, quashing reports that their marriage was supposedlyon the rocks.
Perry is thought to have jetted in from California, with her parents Mary and Keith Hudson - who also attended the event.
The likes of Brand's co-stars, Dame Helen Mirren, and Greta Gerwig also joined them at the premiere.

MTV News was on the red carpet to chat to Russell about his new film, where he revealed that he felt more overshadowed by Mirren than Katy at the event.
Brand explained: "I've been working with Helen Mirren for some time, so I'm more than used to being overshadowed by her."
He added: "She claimed she couldn't do comedy, she claimed she couldn't improvise, she was lying then and she was probably lying when she was pretending to be the Queen - can we ever trust her again? The answer is no."
As for his wife, Russell joked that Perry has "tamed" him, stating: "I think the real Russell Brand, wherever the hell he is, has been tamed....with dog sweets."
