Music producer Jonathan “JR” Rotem has claimed he dumped Britney Spears after she was photographed without knickers late last year.

The couple were spotted together on a number of occasions in November and December, shortly after Britney filed for divorce from husband Kevin Federline.

JR, who is working with Britney on her comeback album, has now said: “Yes, Britney and I were dating, before the crotch-shot thing. Now it’s kind of rocky between us.”

“We’re working together still, but I’m not sure if I want to be tied down, period.”

Perhaps though, she’s better off without him as he went onto reel off a list of his celebrity conquests: “Britney, Mya, Bai Ling, Hayden Panettiere, Meagan Good - it’s a pretty big list, and it’s growing. Britney got me the furthest. She had something special.”
