Actress
Keira Knightley's new movie is packed with lesbina romps.
Keira, 22, and co-star
Sienna Miller soap each other down in the bath, romp naked in bed together and enjoy a threesome with hunky actor Matthew Rhys.
But despite Keira's saucy scenes, she is unlikely to face disapproval from her parents - because the film The
Edge Of Love was written by her MUM.
An insider on the set said: "This is triple-X stuff. There's full nakedness, and the camera spends quite a while lingering over their bodies.
"The girls really got into playing the part. They looked like they were really enjoying it."
Keira and Sienna, 25, who play love rivals in the movie about Welsh poet Dylan Thomas, find their friendship soon gives way to lust.
Keira sits naked in the bath while Sienna - who plays Dylan's wife Caitlin MacNamara - tenderly washes her back. Sienna then strips off and climbs into the tub with her.
A later scene shows the lovers rolling around on a bed in a threesome with Welsh actor Matthew who plays the lusty poet.
The unfaithful Caitlin also romps with dozens of men in the movie. At one point she has sex with Dylan while Keira listens in the bed next to them.
The erotic Brit-flick, set in the Second World War, was penned specially for Keira by her mum, scriptwriter Sharman Macdonald. It is expected to be a huge hit when it is released next summer.
