Jennifer Aniston clingy and jealous?

Only one year after her difficult divorce from Brad Pitt, Jennifer Aniston finds herself single again reports Star Magazine. Her romance with Vince Vaughn officially came to an end last month after nearly a year of dating, and Jennifer fears the break-up is due to Vince’s philandering. Jen is suspicious after Brad’s brutal and speedy relationship with Angelina Jolie, almost immediately following their break-up, and she took that insecurity out on Vaughn.

Sources say that it was Aniston’s over-clinginess and jealous behavior that resulted from Pitt’s betrayal, which drove Vaughn to call it quits. However, it has been reported that Vince never actually cheated on Jen; it is merely easier for her to blame him for problems in the relationship than to confront her own issues stemming from her failed marriage. Since the break-up, Jen has been laying low, staying home and spending time in mediations, while Vince is living up the single life, partying with Kevin Spacey and filming a new movie, and avoiding all contact with depressed and vulnerable Jen.

Looks like Jen had reason to worry. Vince Vaughn was seen publicly cavorting with a mystery blonde in London.

The 'Dodgeball' actor arrived at the aftershow party of '24 Hour Plays', a
London theatre production he had appeared in, with a stained sweatshirt and
his fly undone and then began canoodling with the girl.
