Meanwhile, Aniston and Vaughn have finally admitted they are dating.
The two stars have previously refused to confirm they are an item, but have come clean while promoting 'The Break Up' - which ironically brought them together during the actress' divorce from Brad Pitt.
When quizzed about her first meeting with Vince, Jennifer, 37, said: "For me, it was just wow. You get those moments pretty rarely.
"You can kind of tell pretty quickly with someone, 'Oh, this is going to be easy. Oh, this is going to be a tough one'. He is the cream of the crop."
Vince also admitted he was attracted to the former 'Friends' star the first time he met her - and says he was bowled over by her terrific sense of humour.
He said: "I liked her right away as a person. I think she's terrific.
"Friendship is the biggest thing, and a sense of humour - I like someone who can make me laugh. I think having someone who makes you laugh is really important."

Meanwhile , reviews are flowing in for the Jennifer Aniston and boyfriend Vince Vaughn new movie 'The Break Up'

The Break-Up is not comical or romantic, and it's certainly not a date movie. Sitting through it is almost as painful as going through the demise of a relationship says USA TODAY

This is summer's highest profile romantic comedy (practically the only one), and a movie that carries a special cache from the fact that the stars -- in the wake of the celebrated Aniston-Pitt breakup -- have become a real-life item and tabloid sensation.

But the filmmakers have wildly miscalculated the chemistry these real-life lovers generate on film, the extent to which the audience wants to see their union preserved and how much fun it is to watch them scream at each other for an hour and a half writes Seattle's NWSOURCE

Nobody likes a fight that's fixed, except the backroom boys making the deal. Which is why "The Break-Up," a romantic comedy starring Vince Vaughn and Jennifer Aniston, may have its share of laughs, but isn't much fun writes Washington Post

The Break-Up'' is a silly film about a couple who continue to share a Chicago condo even after they no longer share a bed or a future. It co-stars Jennifer Aniston and Vince Vaughn, who display no chemistry even though they're a real-life item writes Bloomberg
