Billie Piper has confessed that she is jealous of new Doctor Who actress Freema Agyeman.

The 23-year-old, who decided to quit the show earlier this year, admits she gets angry when she sees pictures of the Doctor's latest companion.

"Doctor Who magazine had the new girl on the cover," Billie is quoted by the Daily Star as saying. "I threw it across the room when I saw it. I wanted to scratch both her eyes out. It's like seeing your ex's new girlfriend!"
