Vaughn turns down threesome proposition

Vince Vaughn avoided becoming the subject of a sordid tabloid tell-all by turning down an invite to join two saucy sisters for a sex threesome.

Redheads Liza and Suzi Graves attempted to woo the 'Wedding Crashers' star back to their hotel room after meeting him at trendy Los Angeles bar the Velvet Margarita last week but Vaughn was not interested.
