We spotted Sarah Harding from Girls Aloud out and about in London, running errands in various shops and jumping in and out of her huge car. Now why does a single girl need such a big car? And yes, she is single. We hear that she has split from boyfriend Tom Crane, again! Sarah and the DJ were engaged to be married last year, but then Sarah’s problems led her to rehab and the couple to split. Sarah left rehab and ended up in a relationship with one of her fellow rehab people, which turned out to be disastrous. Not only did Sarah end up back on the booze, but there was an ugly fight over the New Year as they holidayed in a ski resort and Sarah ended up in hospital. Needless to say, that relationship came to an end after that. We then heard the news that Sarah was back with Tom Crane and we all whooped and cheered, and thought she was getting her happy ever after. Until now. She has split with him again, and this time, it doesn’t look there will be any going back. A source said: "It's over. And this time it's for good. Too much has gone on for them to move forward. Sarah is now single and focusing on work." Well that is sad, but we are happy that her focus is back on music again. It is thought that at some point this year, there will be a reunion with the other members of Girls Aloud as they celebrate 10 years as a band. They will give fans a treat with a set of concerts or something similar. Sarah is also meant to be releasing some solo material too.
