Britney Spears was caught banging in the bushes of the Promises Rehab Center with a mystery man.

The wigged-out singer played a game of tennis with the unnamed man, who is also receiving treatment at Malibu’s Promises clinic, before they disappeared together.

The pair were later found getting freaky in the foliage of the grounds and had to be separated by security staff.

“Britney and her new male friend decided to play a game of tennis. Britney is allowed a little more freedom now she’s been in the center a while,” says a snitch.

“The next thing they had sneaked off into the bushes and were getting pretty passionate. They weren’t actually having sex but there was definitely some groping. We had to step in to separate them…..They were told off. They’re in rehab and relationships between vulnerable people aren’t really encouraged,” a celeb tattle dishes.

This is the second time the twenty-five year old has been tied with someone she has met at rehab.

Last week, it was reported that Britney was growing “very close” with rock guitarist Jason Filyaw, who she met at an AA meeting.
