The Bounty Hunter star — who was famously married to Brad Pitt and previously dated Vince Vaughn and John Mayer — says she would consider rekindling an old romance as people can change.
“Absolutely,” Aniston replied when asked if she would get back with a former lover. “When you dated before maybe you were at a time in your life when you’re not ready and not mature enough to make a big commitment. But people change and you learn to accept the good and the bad.”
Meanwhile, Aniston, 41, has blasted claims romantically linking her to her Bounty Hunter costar Gerard Butler.
“I’ve got a very simple life,” she said.
“I have extremely great friends and I have a really lucky career — I’m fortunate.
“All this, that me and Gerry are in this fake relationship for the press of our movie, or the selling of it — it’s just so insulting.”
The pair sparked rumors of a new romance after Butler joined Aniston on vacation in Mexico last month to celebrate her 41st birthday.
And the former "Friends" actress fueled speculation about their relationship when she pulled Butler in for a close embrace while posing for pictures at the U.K. premiere of their movie on Thursday night.
But Aniston insists she is just good friends with the Scottish star and is fuming over claims she has created a fake relationship with him to publicize "The Bounty Hunter."
Speaking on British TV show GMTV, she says, "They think that if you do a movie together and you get on really well you must be dating... I think it's a filler, it's fodder, it fills magazines, it has nothing backing it at all.
"You know there's all this stuff about calculating... that me and Gerry are in this fake relationship for the press of our movie or the selling of it. It's just so insulting at the same time, but again it's the story... I'm getting to a better place in understanding that they're just making money."
And speaking on the red carpet at the film premiere, Butler adds, "I went for her birthday to Mexico. But we're just friends. We have a natural chemistry, you can see it in our magazine shoot and the film; we have a great time together."
“I think that it’s sort of just a formula, that they think that if you do a movie together and you get along really well, you must be dating…it has nothing backing it at all,” she added.
