At one point, Mischa Barton had a fairly promising career. The OC was a hit, she was scoring endorsement deals, and seemed like the next big thing.

Now she is moving from L.A. to London with new boyfriend DJ Ali Love, and is known more for her turbulent personal life than any recent acting work.Linking up with Amy Winehouse should only help that.The UK wild child met a fellow fallen star with wasted potential at a Camden pub yesterday. Soon enough, there was some locking of lips involved.The supposedly-reformed pair were spotted shaking hands then kissing each other before enjoying a chat over a drink or 20. This cannot end well.Amy and Mischa have plenty of common ground to bond over.Winehouse is said to be clean after a high-profile battle with drugs, while Barton announced she is going straight following her most recent DUI arrest.Of course, both have done stints in hospitals and rehab. Mischa Barton was placed on involuntary psychiatric hold last year after a meltdown at home.Now in London to spend time with DJ Ali Love, her new boyfriend, Barton said she's being healthy and has been reading scripts for new acting roles.She told the Daily Mail on Sunday: "I’m avoiding drinking, which is a shame as there’s nothing better than a glass of delicious English Pimm’s."
