Chris Evans unhappy with Billie Piper?

Chris Evans is unhappy that Billie Piper is spending his money on her new love, Amadu Sowe.

The DJ pays his ex a four figure allowance each month, but is becoming suspicious that most of his cash is going towards Piper's new student boyfriend.

"A row's been brewing for ages because Chris believes he may be a sponger," a source told The People. "He's worried Amadu is taking her for a ride while he's studying."

Evans lives close to the Doctor Who actress in Belsize Park, North London.
