Kristen Stewart 'gets totally naked' in new film

Sultry Kristen Stewart is not shy when it comes to getting her kit off, judging by images from her new film.

The sexy Twilight star is seen baring her breasts and bottom in stills from On the Road, which have been printed by the Daily Mail.

It is not clear whether Stewart is currently using condoms with on-off boyfriend Robert Pattinson following reports she cheated on him with director Rupert Sanders - but the new images mean plenty of people will soon get to see her in the buff.

The actress plays Marylou in the film adaptation of the Jack Kerouac novel On the Road and performs alongside Control actor Sam Reilly and Tron: Legacy star Garret Hedlund.

It is directed by Walter Salles and Stewart said the filmmaker allowed the actors lots of freedom when shooting the scenes, noting: "Once we got on set, it was so about just breathing and letting it happen. He put so much trust in us."
