Hilton laughs off engagement rumours

Socialite Paris Hilton has laughed off reports she has become engaged for the third time, after she was spotted wearing a ring on her engagement finger.

The Simple Life star, 25, has been spotted kissing and cuddling on/off boyfriend, Greek shipping heir Stavros Niarchos III in Los Angeles and Miami, Florida in recent weeks - despite their 'official' split in May.

After Hilton was spotted flashing a huge rock on her hand recently, internet rumours surfaced that the socialite has become engaged.

However, her publicist Elliott Mintz says, "Paris is not engaged. She does wear rings on different hands and fingers and depending on what's comfortable, but she is not engaged."

Hilton has been engaged twice - to another Greek shipping heir Paris Latsis last year and model Jason Shaw in 2002.
