Jennifer Aniston would happily get back together with an ex.

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.

When asked if she would get back with a former lover, Jennifer replied: "Absolutely. 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."

The 41-year-old screen beauty has been constantly linked to her 'Bounty Hunter' co-star Gerard Butler and while she says he's "lovely", she insists they're just good friends.

She said in an interview with UK television programme 'GMTV': "Gerry is lovely, he's a real nice guy. But it seems I get linked to all my co-stars. There seems to be a formula - if you make a movie together, then you must be dating in real life. I don't know who starts those rumours but I'm learning to ignore them."

Jennifer and Gerard braved the cold to meet fans at the gala premiere of 'The Bounty Hunter' in London's Leicester Square last night (11.03.10).
