The star pulled out all the stops as she rocked up in a slinky, perilously plunging metallic wrap dress.

However, her decision to go braless proved rather risky as she came close to revealing all as she lent forwards in front of waiting photographers.

Petra further flashed the flesh as the dress featured a thigh-high split which allowed her to show off her endless pins.

She teamed the shimmering number with towering silver sandals and a matching clutch bag.

Adding more bling to her ensemble, the Sports Illustrated model wore a dazzling silver and emerald necklace and matching earrings.

Her blonde hair was styled into loose waves, while her glam make-up was applied to perfection.

Petra appeared to be having fun on the red carpet as she was seen giggling and larking around with a black bowler hat. 

She later took time to pose with fellow model Arizona Muse at the glittering event.
