Sign up for our Royal Family snapchat Braless Olivia Wilde flashes her nipples in plunging scarlet dress with thigh-high split

AMERICAN beauty Olivia Wilde wasn’t afraid to flash the flesh when she donned a seriously sexy scarlet frock and left her bra at home last night.

The .. -year-old actress sizzled in her show-stopping red dress as she filmed a scene for HBO’s upcoming untitled Rock ‘n’ Roll series in New York City.

Featuring a daringly low-cut neckline, the gorgeous number flashed a hint of cleavage while a racy thigh-high split showed off the Tron star’s shapely legs.

Ditching her bra, Olivia brazenly flaunted her nipples beneath the lightweight fabric, and showed off her fabulous figure with a cinched in waistline.

Amping up the glamour with a strappy pair of silver stilettos, oversized cuff, sparkling bag and dangling earrings, the mother-of-one made sure all eyes were on her as she acted out the tense scene. Her brunette locks were styled into loose waves and she sported a polished make-up look with a dark accentuated brow, a sweep of rosy blusher and a pillar box red pout

Olivia has been cast as Devon Finestra in the new drama set in 1970s New York which explores the drug and sex-fuelled music business as punk and disco were breaking out.

Spotted with her co-star and on-screen husband Bobby Cannavale, 45, who plays record label executive Richie Finestra, the pair seemed to be arguing and Olivia even took a few swipes at Bobby.

This is the first time the pair have been seen filming the hotly-anticipated series, which is being produced by Martin Scorsese, Mick Jagger, and Terence Winter.
