Paris Hilton's designer sister Nicky Hilton has dismissed reports she's to marry her TV producer boyfriend David Katzenberg this winter.

The couple has been dating for the past two years, and sources told Star magazine last month that Hilton and Katzenberg were looking at exchanging nuptials in December or January.

However Hilton, who turned 25 on Sunday, tells People.com, "There are no wedding plans. There are lots and lots of rumors but I will put them to rest."
