Anna Friel heads straight home to boyfriend David Thewlis after cosy nights out with young co-star

It's not the typical traffic-stopping after-show exit we've recently come to expect from Anna Friel.

But after recent pictures emerged of her getting friendly with her gorgeous young co-star, she certainly didn't stick around the stage door as she left the Theatre Royal in London's Haymarket last night.

Instead, she headed straight home to long-term partner David Thewlis, who was there to meet her when she arrived.

Since starting her role as Holly Golightly in the West End adaptation of Breakfast At Tiffany's, Miss Friel, 33, has been snapped in a series of stunning outfits as she leaves each night, stopping to sign autographs or pose for the waiting paparazzi.

But it wasn't her glamorous vintage wardrobe getting all the attention last week after she was seen cosying up to 23-year-old Joseph Cross, who plays Golightly's neighbour Fred Parsons, the role made famous by George Peppard in the 1961 film.

Meanwhile, Cross was snapped leaving the Theatre Royal after Miss Friel had left and made a half-hearted attempt to hide his face from the press.

The pair have appeared to have built a good working relationship on the show, which features Miss Friel as the young socialite - played by Audrey Hepburn in the film - who captures Parsons heart.

But they also seem to have developed an intimate social relationship too, something that could be causing tension between Miss Friel and Harry Potter star Thewlis, 47, whom she reportedly met on a flight to Cannes in 2001.

Last Wednesday, they were photographed out together in London snuggling up to each other in posh Piccadilly eatery The Wolesley before they got into a waiting car, with Cross's face smeared in Miss Friel's trademark red lipstick.

The following night, Miss Friel, Thewlis and Cross - who are all said to be good friends - were spotted sharing a taxi as they left the Berkeley Square Christmas Ball.

But on Saturday night, Miss Friel and Cross were once again snapped out alone together with the earlier cuddles turning into a lingering kiss as they shared a cigarette outside a central London wine bar.
