New York: Socialite heiress Paris Hilton informed her fans that she and pop singer Britney Spears are not lovers. The two have been partying regularly together and have stirred speculations, reports newsweek.com. The rumours started doing the rounds when Britney’s ex-husband Jason Alexander, who was married to her for just 55 hours, once said, "She found other girls attractive, yes, but we never did anything about it." In one recent photograph Paris looked like she was stroking Britney’s upper thigh. Another report said Paris was kissing another woman and suggested that she and Britney are more than just good friends. But Paris's representative rebuffs these reports and said, "That is just silly.
