Aniston and Vaughn caught kissing

If you're a Hollywood celebrity, there will always be someone lurking just around the corner, waiting to take your picture. In this case, the celebrity is Jennifer Aniston, and the snapper, People magazine.

In new pictures published today, Aniston is shown kissing film star Vince Vaughn in a private trip to Chicago, possibly ending months of speculation concerning the pair, who recently worked together filming "The Break Up."

Aniston's divorce from star Brad Pitt only became final earlier this month, and she has said that she doesn't want to "be a rebound girl" for Vaughn, after being pressed by Elle magazine on the topic.

Aniston's publicist was not immediately available for comment.
