Keira Knightley doesn't want to sing again, but would if she was able duet with Lana Del Rey.

The star is currently showing off her vocal talents in Begin Again, where she plays struggling singer/songwriter Greta.

Keira has spoken at length about her reluctance to sing, but when ITN suggested that she'd look great on stage with West Coast songstress Lana, Keira's arm was soon twisted.

"OK. Yeah, that would be great. I mean, I don't really want to sing again, but that would be great anyway," she laughed.

The news channel then pondered the possibility of her cast mate James Cordon pulling some strings to make it possible for 29-year-old Keira to collaborate with One Direction.

British actor James is good friends with One Direction singer Harry Styles, so the idea isn't so far fetched.

"No, I think that would be great... Totally. Yeah, sure. Are you going to sort it out? You should [pitch it to him]. I think he'll be over the moon," she giggled.

Begin Again co-stars Mark Ruffalo and Maroon 5 crooner Adam Levine, marking the singer's first foray into the movie world.

Shot on location in New York, Keira admits that getting in people's way was a constant struggle for the cast and crew.

"The thing about New York is everybody's very cool, so nobody's very impressed. So many things get shot there that they're not... all they want is for you to get out the way. So I think we got shouted at quite a lot. And really the whole game of the film was to try and get the scene done before we got shouted at," she divulged.

"I think it would maybe be slightly different in England. I think actually we'd be politer, just be a bit like, 'Oh sorry, are you shooting a movie? Oh no, I'll get out the way'. Whereas they were just like, 'Get off the sidewalk!'"
