Here is Sarah Harding from Girls Aloud walking around London after lunch... and not just any lunch, lunch with a mystery man. This is Sarah’s new boyfriend – and we guess they are so in love already that they are wearing matching outfits.... jeans, green coats and brown boots... they really do look similar don’t they. Except their colourings – she looks like she’s done the fake tan a lot more than him. We don’t know who exactly Sarah’s new boyfriend is, although we do know that they have been spending a lot of time together. He obviously has her family’s approval as he was out shopping with them last week for a Christmas tree. Sarah really does seem to move on fast. She only got out of rehab a matter of weeks ago, and at first was back with her DJ fiancé Tom Crane – one minute they’re holding hands, the next thing we know, it’s over with Tom and she has a new older man! Sarah went to rehab after her engagement with Tom was called off. She went in to deal with depression and alcohol abuse. She spent a month in the facility in Arizona in America and it seems to have sorted her out. It has been revealed that Sarah underwent equine therapy during her time there to try to tackle the hurt caused by the breakup and her other issues. Sarah has talked this week about some of the processes that she had to go through. One of them was reading damage letters sent by her loved ones about the impact her drinking had on them. She said: “They don't let you see it before you read it out loud to the group so it's tough because you've got acceptance to deal with as well. My mum wrote one and I sobbed and sobbed when I read that. Tom wrote one too. My counsellor showed me photographs of me coming out of clubs totally hammered. I felt really ashamed.' Well, Sarah it’s good to see you looking better!
