Alexa Chung and Josh Hartnett were "all over" each other at Bungalow 8 nightclub last night. The couple, who have denied rumours of romance between them, seemed to be taking their friendship to a new level. The pair arrived together at the Covent Garden club and sat next to each other in a corner with some chums.

But wait a minute! Isn't Alexa supposed to be dating (indeed living with) Alex Turner from the Arctic Monkeys?

Getting cosy: Josh Hartnett and Alexa Chung

What Alex is going to make of the news that his girl was flirting outrageously with a Hollywood heart-throb is anyone's guess - although we imagine he'll go ape.

Our spy in the club said: "Alexa was living any girls fantasy, with her hands all over Josh. They were sitting very close together and flirting.

Josh even affectionately pulled Alexa's ears a few times, and they seemed very happy cuddling each other.

"They were sitting with a group of people in a corner at the back of the club. Josh ordered a tray of shots, which he shared with Alexa and a few of his friends. They were clearly having a lot of fun, and looked like they were really into each other."

Alex and Alexa have been going out since July last year, and he won't like reading about her antics with Josh. But it might be some comfort for him to know that they did not kiss and left separately.

Our source continued: "Although they were so close, they didn't kiss. They left the club together but Alexa waited in the foyer for Josh to leave before getting into a car with a couple of girlfriends. Josh went back to his Soho hotel with a couple of gal pals."
