Paris Hilton and Stavros NiarchosParis Hilton’s spokesperson has denied that the heiress is engaged to on-and-off boyfriend Stavros Niarchos after she was spotted with a glitzy diamond ring on her engagement finger.

Paris and Stavros - and Paris’s finger gem - were spotted out and about together in Los Angeles last week and then again in Florida over the weekend.

The pair were seen looking loved up at the Ink nightclub in South Beach, Florida on Friday night and Paris even treated Stavros to a lapdance before the party, which included Paris’s sister Nicky Hilton and Brandon Davis, moved onto the Mokai club in Miami Beach.

A source told People magazine: “Not only are she and Stavros together, but they are in love.”

Elliot Mintz, Paris’ publicist, though hit back against the engagement rumours: “Paris is not engaged. She does wear rings on different hands and fingers and depending on what’s comfortable, but she is not engaged.”
