Vince Vaughn thrilled baseball fans at Wrigley Field in Chicago, Illinois on Monday (29MAY06) by leading sports anthem TAKE ME OUT TO THE BALL GAME during a Chicago Cubs game. The actor, wearing a Cubs shirt, threw out the first pitch and crooned the baseball tune over the stadium's tannoy system as girlfriend Jennifer Aniston watched proudly from the terraces. The couple was in Chicago checking out Vaughn's beloved Cubs before attending the local premiere of new film THE BREAK-UP, which was filmed in and around the city.
