It was a style showdown in London on Tuesday, as Arthur stars Helen Mirren and Greta Gerwig got some fierce red carpet competition from Russell Brand‘s chart-topping wife Katy Perry and RadarOnline has all the photos.
Katy Perry left the boho babe at the Coachella Music Festival, where she was partying over the weekend, and rocked a curve-hugging, one-shoulder Philip Armstrong gown. The glammed-up gal paired the nude, impeccably embellished number with matching Brian Atwood pumps for a flawless finish. Her hubby Russell Brand was also dressed to impress in Dolce & Gabbana.
Finally, indie spirit turned bigscreen babe Greta Gerwig opted for a more ‘mature’ look with a short-sleeved, dully-colored floorlength number, which she paired with cream sandals and a matching clutch.
