Elizabeth Hurley, 54, rocks sexy ninja costume with knee-high boots: 'Oh behave'

She’s one of the sexiest women alive, but Elizabeth Hurley, 54, still gets silly, this time posing in a sexy ninja costume on Instagram.

The British beauty shared a series of photos on Friday hamming it up with friends in a cleavage-bearing black-and-red hooded leotard, a black face mask and thigh-high boots. “Ninja night,” wrote Hurley with the hashtag #Xmas. The star appeared to be enjoying a costume party, as the other revelers were dressed in similar gear.

Fans were pleased by the revealing costume. “Hit me! Hit me!” joked one. “Oh behave,” remarked another, a line from Hurley’s 1997 film Austin Powers: International Man of Mystery. “You can mortal combat me any day!” someone wrote. And several begged for a glimpse of the costume from behind.

This week, Hurley spent her holiday modeling a glittery gold dress and also, a pair of black bikini bottoms with a matching blazer, unbuttoned to reveal she wore nothing underneath.

She also shared a photo of her and 17-year-old son Damian Hurley, a professional model who just landed a gig for Pat McGrath’s new makeup campaign. The selfie provoked comments that the mother and son were mirror reflections.

On her new post, a fan of Hurley’s commented that the ninja get-up would be perfect for a New Year’s Eve masked ball. Knowing the superstar, she’s already planning a smoldering January look.
