Singer Lily Allen’s new relationship is reportedly in trouble, femalefirst.co.uk reports.

Allen and producer Robertson Furze are said to be having blazing arguments over her reportedly difficult behaviour.

A source close to the couple — who moved in with each other last month just weeks after they started dating — told Britain’s Closer magazine that things “just aren’t going well” for Allen.

“She and Robertson aren’t getting on brilliantly. He says she’s too demanding, over-emotional and dramatic,” the source said. “They’ve been seeing each other for a few weeks but it doesn’t seem to be going anywhere. She’s saying she doesn’t see him as a serious long-term boyfriend material. It’s fizzling out before it really started.”

Friends also say Allen isn’t over her ex-boyfriend Ed Simons.
