AMERICA wants famously jilted Jennifer Aniston to settle down with boyfriend Vince Vaughn

Page Six is reporting that test audiences for The Break up wants Jennifer Aniston to settle down with boyfriend Vince Vaughn .

A Page Six spy reports, "The original screenplay had Jennifer and Vince's characters breaking up at the end. So it was shot that way - but test audiences hated it. It tested really - and I mean really - badly."

So Aniston and Vaughn, who met while making the picture and subsequently fell in love, were sent back to Vaughn's hometown of Chicago to do reshoots, costing Universal millions.

"The new ending has them getting back together in the end. It should really be called 'The Make Up,' " snickered the source.

"People want to see Jennifer happy after she was thrown over by Brad Pitt for Angelina Jolie," added another insider. "And with the original ending - well, it was just too much of the same."

A rep for Universal says: "Every film can benefit from a few extra days of shooting, and 'The Break Up' was able to return to Chicago for some quick additions that we believe will add to what we know is already an enormously satisfying movie."

While in Chicago, Aniston and Vaughn, according to witnesses, have also been house hunting and checking out luxury penthouse pads in the city Aniston seems to want to call home.
