Former Reality show star Paris Hilton may be in hot water with her rock boyfriend Benji Madden, after photos were published of her and former beau Stavros Niarchos flirting in a nightclub. Paris was spotted getting friendly with her Greek shipping heir ex, who she dated for more than a year before they split in 2006. But the star seemed to be good terms with her former lover as they partied together in Miami hot spot Mokai nightclub this weekend. In the pictures, Niarchos can be seen stroking the blond beauty's hair as he intimately whispers into her ear. Hilton looks happy to be in his company, despite being in a serious relationship with Madden for over eight months. A source tells Britain's The Sun newspaper, "Stavros looked thrilled to see Paris again and was spotted stroking her hair. They then looked deep in conversation."
