Salma Hayek, 57, is ever the brunette bombshell in busty optical illusion dress as she arrives at Miley Cyrus' Gucci bash in LA

Salma Hayek proved she's still a total bombshell at 57 as she arrived at a Gucci event on Thursday night.

The invite-only summer soiree was hosted by Grammy Award-winning singer, Miley Cyrus, 31, at swanky Chateau Marmont in West Hollywood.

Cyrus is the face of the Italian luxury designer's popular Gucci Flora fragrance line and recently appeared in a new campaign.

Meanwhile, Hayek's Gucci connection is through her billionaire husband François-Henri Pinault, who is president of LVMH which owns Gucci and other luxury brands.

For the event, the Oscar nominee sizzled in a busty blue floral print frock that showed off her enviable curves.

Black silk paneling on the sides and back of the dress helped exaggerate Hayek's hourglass shape.

She exited a chauffeured SUV wearing sky-high black platform heels.

The Frida star carried a small black purse and accessorized with sparkly silver jewelry.

Hayek's raven hair was worn sleek and straight and she opted for a dramatic glam makeup look.

She was accompanied by her glamorous stepdaughter Mathilde Pinault, 23.

Mathilde — who is an aspiring model and equestrian — rocked a Gucci crop top and flared blue jeans for Miley's big bash.

Hayek became Mathilde's stepmom after she and Pinault tied the knot in 2009.

The couple — who celebrated their 15th wedding anniversary in February — share one child: daughter Valentina, 16.

Salma's appearance in LA on Thursday comes after her recent whirlwind trip to the United Kingdom.

She was in London to attend Wimbledon with a slew of other A-list celebrities.
