Jennifer Aniston and Vince Vaughn were photographed kissing, possibly confirming that their relationship has grown romantic. People magazine published the photos, taken last week in Chicago, in its Oct. 31 issue, on newsstands Friday.
Reports have swirled for months that the two actors were an item. Previously, though, it was impossible to separate fiction from reality since they were at work filming The Break Up. This time, the co-stars were without a film crew while they spent several days together in Chicago, Globe and Mail says.
A call to Aniston's publicist was not immediately returned.
Her divorce from Brad Pitt became final Oct. 2, concluding 4-1/2 years of marriage.
Vaughn co-starred earlier this year with Pitt and Angelina Jolie in Mr. & Mrs. Smith. It was then that reports of a romance between Pitt and Jolie began, which were later corroborated by photographs and public spottings.
In interviews, Aniston, 36, has denied a relationship with Vaughn, 35. In this month's Elle, she said, "He's delicious and funny ... but I don't want to be a rebound girl."
Last month, she said on The Oprah Winfrey Show that she was ready to date again. In response to Winfrey's query about Vaughn, Aniston responded, "Oh, Oprah!"
Aniston will next star in Derailed with Clive Owen, to be released Nov. 11. The Break Up is scheduled to hit theaters in February. Vaughn's screen credits include Swingers and Wedding Crashers.
