Hilton laughs off Grenier romance

Socialite Paris Hilton has laughed off reports she is dating Entourage heart-throb Adrian Grenier, insisting they are just pals.

The hotel heiress has been romantically linked to a string of famous men this year, including James Blunt, Josh Henderson, Cisco Adler and NASCAR driver Kasey Kahne.

After Hilton and Grenier were spotted frolicking on a beach in Malibu, California, last week, gossips began speculating they were dating.

However, Hilton's rep says: "They are just friends. There's nothing between them."
