Carey Mulligan shimmers in sparkly black dress as she swaps mommy duties for a night out at Hollywood Film Awards

She flew into LA in full mommy mode cradling her baby daughter but a day later, Carey Mulligan was all Hollywood glamour at a star-studded awards show.

The 30-year-old actress shimmered in a below-the-knee black cocktail dress with a layered skirt and a cross halter neck.

She matched the sequins embedded in her frock with a pair of black and silver pumps.

The new mom left her shoulder-length brunette hair loose in soft curls and added some diamond earrings.

Mulligan, who stars in the film Suffragette with Meryl Streep, was at the event to pick up the Hollywood Actress Award.

She looked so stunning it was hard to believe she'd given birth to daughter Evelyn just five weeks ago.

The Great Gatsby and An Education beauty gave the world a first glimpse of her infant daughter after she touched down at LAX Saturday with husband Marcus Mumford.

As they exited the airport, Mulligan carried Evelyn in a front sling with the little girl bundled up in a onesie and knitted cap.

The actress kept a protective hand placed gently on her head as she followed her husband who was pushing their luggage on an airport cart.

The couple, who wed in April 2012, have kept their baby out of the spotlight and have rarely spoken about her publicly.

But as Mulligan promoted her new film Suffragette, she let a few tantalizing details slip about being a new mother.

She revealed her daughter's name last week at the New York premiere for the film and she admitted to E! News that promoting a film while nursing an infant is not easy.

'The last couple of weeks have been pretty stressful,' she said. 'Doing press and doing it with a tiny baby, timing has been very important and babies do what they want, which is a challenge.'
