Billie Piper has been accused of 'stealing' her new boyfriend from another woman.

The Doctor Who actress started dating Laurence Fox this month after ditching her boyfriend of two years, Amadu Sowe. Fox had been involved in a relationship with 29-year-old Martha Swann for six years and pals had expected him to marry her.

"Martha's really gutted by what has happened," a friend told The People. "She thinks Billie's to blame for the split. She'd been going out with Laurence for a total of about six years and then this happens. That's a long time to be with someone and for it all to end so suddenly.

"I know Martha thought she and Laurence were on the verge of getting married. She was thinking further down the line and obviously Laurence wasn't. She is really upset."
