She’s working hard on the promo trail for her new movie, the X-Men sequel Apocalypse.

But Jennifer Lawrence found some time to enjoy London‘s nightlife on Sunday as she hit the town in a very daring ensemble.

The US actress made the most of the balmy UK temperatures in a skimpy crop top and sheer skirt as she enjoyed dinner at the capital’s hotspot Sexy Fish before heading to the Connaugh hotel for drinks.

She added a smart black blazer over the top but flashed even more flesh with her daring choice of skirt.

The sheer black number showed off her long legs, with a panel at the top preserving her modesty.

Jennifer finished off her outfit with a pair of statement black sandals, with pretty gold detail while she carried a coordinating clutch bag.

The gorgeous big screen star swept back her blonde locks into a chic up do and added shimmering eye makeup and a glossy pink lip.

Jennifer was escorted out of the restaurant to her car by a dapper minder, as she headed to her hotel for a nightcap.

It’s been a busy few days for the star, who has been promoting her new film across Europe.

Jen made sure she made a stunning sartorial effort as she attended a photocall in London earlier on Sunday.

The Oscar winner went for an ultra feminine look in a low-cut coral, paisley Altuzarra maxi dress and gold strappy sandals as she joined her co-stars at the Claridge’s Hotel.

The 25-year-old joined a host of her co-stars, including James McAvoy, Sophie Turner and Oscar Isaac, for media interviews at the five-star Mayfair hotel.

The latest film in the hugely popular X: Men film sees Jennifer reprise her role as the mutant Mystique and her human form Raven Darkholme.

She previously played the red-haired, blue-skinned mutant in 2011 film X-Men: First Class, and 2014’s X-Men: Days of Future Past.
