Mischa Barton has laughed off reports that Nicky Hilton called her a "fat pig".

'The OC' star says she doesn't care what Hilton thinks of her and believes the comment reflects badly on the hotel heiress.

She said: "If Nicky really made that remark it says more about her than it does about me."

Nicky - sister of socialite Paris - was apparently horrified to see the stunning actress at a star-studded bash at the swanky Regent Beverly Wiltshire on Saturday night (28.01.06).

According to a report in America's New York Post newspaper, Nicky snapped: "What is that fat pig doing here?".

She then fled to the other side of the room.
