Paris Hilton may be in hot water with her rocker boyfriend Benji Madden - after snaps of her and former beau Stavros Niarchos flirting in a club were published.

The socialite was spotted getting friendly with her Greek shipping heir ex - who she dated for over 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, Florida hotspot Mokai nightclub at the weekend.

In the pictures, Niarchos can been seen stroking the blonde beauty's hair as he intimately whispers into her ear.

A gleeful Hilton looks happy to be in his company - despite being in a serious relationship with Good Charlotte star 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."
