Sarah Harding back with ex Tom Crane

Sarah Harding and Tom Crane have got back together.

The Girls Aloud singer and the DJ called off their engagement in September but after holding talks have decided to give their relationship another go.

Tom flew out to the US to support Sarah while she is undergoing treatment for "depression and alcohol addiction" at a facility in Utah and their heart-to-heart talks resulted in the pair agreeing to stop partying for the sake of their romance.

A source told The Sun: "Sarah and Tom are back together with sanctions from Tom about their lifestyle. They've been having heart-to-heart chats and the outcome is that they're going to try again.

"They feel like they've been through too much together to let it go."

The pair - who had been dating since 2007 and were planning a huge wedding celebration for next year - ended their relationship after having a series of bust-ups about over the summer about Tom working constantly in Ibiza, leaving Sarah to shoot the film 'Run For Your Wife' in the UK on her own.

But since the singer-and-actress checked into rehab the pair have realised how much they mean to one another.

The source added: "Tom has flown out to be with her and help her through her problems. He felt partly responsible. They've been living a healthy lifestyle and rediscovering why they fell for each other in the first place.

"They both believe they can come out of this stronger than ever."

Although the couple are back together they are not going to rush into getting married and have put all plans for their nuptials on hold.
