Naked ambition: Jennifer Lawrence did not let the sartorial prowess stop there as she headed to the after-party for the the star-studded Dark Phoenix premiere in a sizzling nude gown which flashed her assets

Jennifer, who was joined by her ex-beau Nicholas Hoult on the red carpet looked stunning as she cosied up to co-star Sophie Turner.

The glittering nude gown made the most of her lithe physique as the spaghetti straps and low-back perfectly hung from her frame.

She kept her beauty look simple with her blonde tresses teased into loose waves, in the same style she rocked earlier in the evening.

During an appearance on the Tonight Show, Jennifer told Jimmy Fallon that it originally took eight hours to paint her entire body blue to play Mystique.

Hot stuff: The 28-year-old actress, who plays Mystique in the superhero franchise, looked incredible in her second look of the night – with the nude gown perfectly hanging off her sensational frame to best show off her assets

For her second X-Men film, Days Of Future Past, the Silver Linings Playbook star refused to do the body paint, instead sticking to makeup above her shoulders and a body suit for everything below, though the prep process was still lengthy.

The outspoken actress didn’t mince words when it came to the how the new film wrapped up her portion of the X-Men series.

‘I was blown away, really,’ she said. ‘They did not hold back with the ending of this movie, and it was quite emotional.’

Wow! She kept her beauty look simple with her blonde tresses teased into loose waves, in the same style she rocked earlier in the evening

Also at the premiere was Jennifer’s co-star and former boyfriend Nicholas. The two struck up a relationship in 2010, while filming the first of the rebooted X-Men movies, X-Men: First Class. The Tolkien star played Beast, a blue-furred, wolf-like mutant.

The actors ended their relationship in 2014 toward the end of filming for X-Men: Days Of Future Past, though they’ve since remained friends and co-workers.

The two were spotted sharing a laugh from the red carpet outside the Chinese Theatre.
