Music producer JONATHAN 'J.R.' ROTEM has confirmed he dated Britney Spears just weeks after she separated from ex-husband KEVIN FEDERLINE in 2006. Rotem claims he and Spears decided to end their brief romantic involvement, which took place in December (06), for the sake of their careers. He tells U.S. magazine Blender, "Britney and I were in a relationship. We were dating for about two weeks but decided for both our careers that it wouldn't be cool to have a romantic relationship. "She was really emotional and distressed at the time."
