PINK LADY! Katy Perry matches her fuschia-coloured dress to her hair for an evening at Nobu in London. The "Last Friday Night" singer left the popular restaurant at 12.30am via the back door and was greeted by a mob of photographers. (Pacific Coast News)more pics Katy Perry (Pacific Coast News) Katy Perry made sure to match her hair to her dress on her recent night out at Piccadilly Theatre. The pop star paired her pink hair with a fuchsia dress and caplet. The pop star hit the West End theater scene with her mother-in-law Barbara Brand for the musical adaptation of Ghost.

The night out with Russell's mom quickly did its part to dispel tabloid rumors that the Perry-Brand union was on the rocks. After appearing on The X Factor without her wedding ring, the internet buzzed with talk that she and Russell were on the outs, but a girl's night with Momma Brand and photos of Perry once again sporting her ring say otherwise.

Russell was unable to accompany his two ladies, as he is currently touring Canada with his comedy show Russell Brand Live. Check out more photos of Perry's pink ensemble and her night with her hubby's mummy:
