He's the film director whose box office smash Hostel was dubbed 'torture porn'. She's a socialite nearly half his age, famous for being the daughter of a pop star.

But it seems Eli Roth and Peaches Geldof have found common ground.

The grinning pair posed for the world's paparazzi hand in hand as they arrived for the prestigious Vanity Fair post-Oscars party last night.

They then sat entwined and deep in conversation at the bash.

Eli wrapped a possessive hand around 20-year-old Peaches' leg, while she in turn grasped the 37-year-old's arm.

Peaches made no secret of their togetherness, telling her thousands of fans on Twitter: 'At the Vanity Fair Oscar night party with @elirroth who's got a silent movie star look going down tonight. Very sharp.'

She later tweeted: '@eliroth shouted "word" into a microphone p.diddy thrust in his face whilst jumping on a couch. S*** just got real.'

Where the pair met is unknown.

Roth acted in one of this year's big Oscar films, Inglourious Basterds.

The New York-born son of a Harvard psychology professor and a painter, his 2005 film Hostel was made on a shoestring budget of just $4million, taking more than $240million at the box office and on DVD.

It was dubbed 'torture porn' by critics for its gruesome content, and led to a flood of copycat films.
