Mischa Barton was snapped here kissing model Irina Lazareanu @ the "Caviar Kaspia" restaurant in Paris, France. The two friends were celebrating Mischa's 23rd b-day!

If you're wondering... yes, this is the same Irina that was dating Pete Doherty after his break-up from Kate Moss early last year. And no, I don't think Irina and Mischa are being serious. Because, it's rumoured that Mischa is already spoken for. According to MTV:

Mischa Barton and the Kooks frontman Luke Pritchard reportedly couldn’t keep their lips off each other at a London comedy club last night.

The pair was photographed at the club for the first time together, following weeks of speculation that the couple are dating

Apparently not shy of showing public affection, the curly haired singer could be seen pecking on the actress’ earlobe, to which she responded with a full on kiss.

Luke spoke of Mischa last month, saying: “I’m very lucky. She’s beautiful, so I feel lucky she decided to go out with me.”

Adding that: “It came about because we have lots of friends in common and kept going to the same parties.”

How sweet is this guy!? Let's just hope he turns out be a much better than Cisco Adler and doesn't pose full frontal. I'm happy for Mischa... Luke seems really nice!
