Emmy Rossum turned heads with other fellow celebs at a lavish bash thrown by British designer Antonio Berardi on Tuesday, January 7, at Mr. Chow.

Along with the Shameless actress, Kate Beckinsdale, Nicole Ritchie, Diane Kruger, Joshua Jackson, and Dita Von Teese were also in attendance.

Beckinsdale and Rossum honored the designer by wearing his dresses at the event. Beckinsdale looked gorgeous in a monochrome racer neck sheath dress from the designer’s Resort 2014 collection. She paired her black and white frock with black strappy heels and a matching clutch. Of course her best accessory was her director husband Les Wiseman on her arm.

Not to be outdone, Rossum turned heads with a lime-green evening dress from the designer. Her porcelain skin glowed against the brightly-colored frock, and her dark, long hair provided an elegant and striking contrast. The actress also sported black heels and a clutch to finish the look.

Apparently, this night out is good news for Rossum, who suffered from food poisoning over the holidays while on vacation. Rossum alerted her fans of her illness by posting this on Twitter:

Food poisoning on vacation is the worrrrrrst. #holiday #epicfail

Rossum has been busy promoting season four of Shameless, and was recently spotted by paparazzi filming a scene in which she shed a few tears. She went to Twitter to share her experience:

There's nothing quite as bizarre as trying to ignore paparazzi while you're imagining your family dying to make yourself cry in a scene.
