Jennifer Aniston News - Engaged to Vince Vaughn?

Rumor mills have reported the Vince Vaughn and Jennifer Aniston news of a supposed engagement since they were seen hugging on the set of The Break Up last year. Jennifer Aniston vehemently denies any news of an engagement or even that they are dating in the first place. Now, there appears to be some solid material evidence to the contrary. Vince has apparently gifted Brad Pitt's ex with an enormous diamond sparkler for her hand. Reps for Vince claim that the ring is nothing more than "a token of his affection" for the actress and that they are not engaged to be married. Valued at over $500,000, that sure is some 'token' on Vince's part. Sounds like Vince must be really, really fond of Jen.
