Who's got the advantage in Paris Hilton's court? In one weekend tennis stars Andy Roddick, 22, and Mark Philippoussis, 28, were both allegedly the objects of the 24-year-old star's affections. On Oct. 24 the hotel heiress told reporters, "I'm head over heels" for Australian Philippoussis – and reportedly held up a shirtless picture of him on her cell phone. But then she was spotted kissing Mandy Moore's ex Roddick in Las Vegas, though his rep denies the encounter took place.
