Keira Knightley Moving in With Beau!

After becoming concerned that he was getting too close to his glamorous co-star Sophia Myles, the Atonement actress has told friends she and Rupert are planning to buy a £2million home together in London's Notting Hill.

The news comes after the couple have been going through a bit of a wobble. Friends say they have been arguing about Rupert's workload and how little time they spend together.

Rupert, 26, who met 23-year-old Keira on the set of Pride & Prejudice, is now filming Buddha's Little Finger with Sophia Myles, 28, but has also just wrapped three other movies and has been working solidly for six months.

"Keira was quite concerned they were drifting and he was getting a bit too close to Sophia," says a friend. "So she flew to the set in Germany and they sorted things out. It was then that they decided to buy a house together and they are going to put in £1million each. "Keira has turned down all scripts for the time being so she can spend more time with Rupert. The problem is he has been doing back-to-back projects for months."

Keira currently lives with her brother Caleb in a flat in Hyde Park, with Rupert a regular house guest. It has been reported that Rupert's lawyer mother will be negotiating the contract.
