Chicago, May 29, 2006 – Chicagoans came out in droves on Memorial Day to welcome native son Vince Vaughn at the premiere of his new film, The Break-Up. Huge crowds packed North Southport Avenue in front of the Music Box Theatre, where co-star Jennifer Aniston arrived first, walked the red carpet and gave a few interviews. Once she entered the theater, Vaughn’s car pulled up, and as he emerged, the mostly female fans went wild; police had difficulty holding them back.

It seems that despite the release of their first-ever photo spread together, in Entertainment Weekly, Aniston and Vaughn haven’t gotten any more comfortable about displaying their feelings publicly; it was exactly one week ago today when the two behaved like strangers at the romantic comedy’s Hollywood premiere.

However, Windy City sources told us that Chicago Cubs fan Vince took Jen to a baseball game in the afternoon on Monday, and that they finally sat together by the third inning. The Cubs won, breaking out of a bit of a slump, to Vaughn’s delight. (Readers: if any of you were at the Cubs game, please e-mail with reports – on Vince and Jen, not on baseball.)

The day’s heat and humidity lifted a bit when clouds threatened the evening premiere, and there was a little rain, cooling things off slightly for the after party at the Lincoln Park Zoo.
