Keira Knightley open to collaborating with fiance

Actress Keira Knightley refuses to rule out a collaboration with her rocker fiance James Righton, insisting it would be "lovely" to work together.

The British beauty admits she would be willing to team up with The Klaxons star after being inspired by Steve Carell, who worked happily with his actress wife Nancy on their apocalypse movie Seeking A Friend For The End of the World.

Knightley says, "I've never worked with a significant other but I should imagine it would be lovely. When you get together I don't see why you shouldn't get on when you are working together."

But despite preparing to marry a singer and keyboardist, Knightley insists she has never been a huge music fan.

She adds, "It's weird because a lot of my close friends and relatives are totally obsessed by music and even though I'm not, I've always, for some reason, been attracted to people who are."
