Pirate of the Caribbean actress Keira Knightley has hinted her relationship with Rupert Friend is on the rocks.

The British actress - who is currently starring in the West End show The Misanthrope where she portrays 22-year-old movie star Jennifer - has spoken about the similarities between her and her sexy on-stage persona, admitting they both have love life “problems.”

“Do I recognize being an extremely well-known young actress? Yes. And she’s in the middle of a world full of people who are quite a bit older than her. She’s having a problem with her boyfriend. No comment.”

The 24-year-old beauty - who has been dating Rupert, 28, since 2005 when they met on the set of Pride and Prejudice - also admitted she doesn’t view fame in a positive way because the definition has changed so much.

“If I’d thought about what fame meant when I was younger, it probably would have been for your name to be respected for something you do well. I don’t know that that is any longer what fame means. I don’t see it in its modern-day connotations as a particularly positive thing.”
