Meanwhile, Jennifer Aniston's "guarded" relationship with Hollywood funnyman Vince Vaughn is the result of her parent's divorce--not Brad Pitt--a friend of the star insists.

The Break-Up co-stars have infuriated the press and fans while promoting the movie this month by refusing to confirm their dating status, and Aniston has proved particularly wary of discussing her feelings for Vaughn in interviews reports Hollywood.com.

However, close pal Jim Cruse insists her reluctance to show affection isn't the result of her traumatic split from ex-husband Pitt last year, but her troubled childhood with her father.
