Jennifer Aniston and Justin Theroux are moving back to New York.

The couple - who have been dogged by rumors their relationship is in trouble - have been based in Los Angeles, but with the actor undertaking several commitments in the Big Apple this year, his fiancee has agreed to relocate with him so they can spend more time together.

"Jen and Justin have talked at length about the possibility of moving back to New York to give their relationship a proper shot because at the moment they are barely seeing each other. Justin can't leave New York for the foreseeable future because he is filming The Leftovers, so Jen has agreed to move back there predominantly so they can make it work and be together. Jen and Justin decided this was the only answer if they want to stay together because having a long-distance relationship just wasn't working out for them," a source said.

The couple plan to make the move later this month, and though Jennifer is expecting the change to be tough, she thinks the sacrifices she is making are worth it. "The real gesture is being made by Jen, because she's got two movies in production at the moment, so taking time out to be with Justin is a seriously big deal... It will be hard, as Justin will be working long hours filming and she will be away from many of her closest friends in Los Angeles but she thinks it is worth a go and will make trips back to LA, of course," the source added.
