Nicky Hilton was photographed on her way to big sis Paris' Christmas party with her latest squeeze David Katzenberg.

For those of you who don't know who little Davie is, he used to date Mary-Kate Olsen...Paris' current flame Stavros is also Mary-Kate Olsen's ex. Leftovers must be popular this holiday season.
