Natalie Dormer courted attention when she stepped out in St Tropez to enjoy a night with friends on Friday.

The Game of Thrones actress slipped her svelte form into a slinky black dress which was slashed to the thigh, revealing almost the full length of her slender legs.

Natalie, 33, also flashed a glimpse of side-boob as the full-length frock featured a loose open back which fell forward to expose a fraction of her right breast.

'F*** who doesn't like my heart': Natalie Dormer held up an explicit sign as she was spotted on a street in St Tropez on Friday night

She opted for comfort over style and teamed the dress with a pair of flip-flops.

However, her outfit wasn't the main attraction as she was pictured holding up a piece of paper with the words, 'f*** who doesn't like my heart' scrawled across it.

Natalie deliberately waved the sign in the eye line of the pap pack as she chatted with friends outside a parked vehicle.

On the defence: Natalie defended the 'real and dirty' sex scenes in GOT in a recent interview

The Hunger Games actress' outing comes after she defended the GOT sex scenes earlier in the week.

Talking in an interview with The Telegraph, she said: 'I think sex and romance is a huge part of human motivation. So long as it's informing the story then I don't see what the problem is. Obviously no one likes gratuitous sex or gratuitous misogyny, the same way people shouldn't like gratuitous violence.

'But I think Thrones is quite good in that way. The violence is quite naturalistic. It's not hyper-stylised. It's not glamorised. And the sex is quite real and dirty as well. It's about those raw, visceral qualities of human life that make good drama.'
