Sienna Miller has fled to Los Angeles following her split from Rhys Ifans. The 'Factory Girl' actress decided to make the move after Rhys' close-knit circle of friends made her life difficult in London.

Sienna ended the relationship earlier this month, leaving Rhys, 39, heartbroken. His pals believe the only way he will manage to get over the split is if Sienna, 26, is out of the country.

A source told Britain's Daily Star newspaper: "Sienna was prepared to be ostracised but then she got a call from one of Rhys' friends she calls 'The Don'. "

She said that it had been suggested she get out of London for a bit to give Rhys time to get over their split, or face the consequences as far as her career was concerned. It was intimated that certain strings would be pulled if she didn't agree."

Sienna has instructed a top estate agent to find a tenant for her London house, and has been already started looking for a new property in Hollywood.
