Rumors have been circulating forever about Orlando and Kirsten ever since they did Elizabethtown. At the time, Orlando was with Kate and Kirsten was on and off with Jake. When Kirsten was asked about their relationship back then she adamantly denied anything was going on, saying, ""If you're alluding to whether Orlando and I got together then that's a no. No." Well, she was either lying or she's had a big change of heart because the two were evidently all over each other at Chateau Marmont last week. The Daily Mail reports:

"They were kissing and cuddling in the corner of the lobby bar and didn't seem to care who saw them. They even stayed past closing time because they were enjoying each other's company."

The Chateau Marmont is not the place to go if you want to keep a blossoming romance under wraps, one source tells us, adding: "It's like coming out without actually issuing a statement."

Orlando and Kate broke up in September after a rather tempestuous four years. A close pal of Orlando tells us: "Kirsten reminds him of what Kate used to look like before her dramatic weight loss. It was so much fun for him to be with her because she seemed carefree and not obsessed about fattening foods. Kirsten can also let her hair down a bit and isn't worried about being the most fashionable girl in the room.

"Orlando likes that she can look a bit dishevelled, he thinks it's sexy. Kate would never go out unless she looked perfectly coiffed and that got a bit tiring."

It's clear there's something between them. They always looked into each other when doing photoshoots for Elizabethtown.
