Chace Crawford and Ed Westwick are still at the centre of homosexual rumours, after a bunch of flirty girls were unable to separate them at a recent concert.

The Gossip Girl co-stars are close friends, but their recent display of solidarity at a gig by British popstars The Ting Tings has prompted some to speculate they are more than just pals.

A spy tells New York Daily News: "They were never more than a foot apart. It was freaky. If one moved two feet to the left, so did the other."

The pair also chose to ignore a number of flirty girls vying for their attention. "They were only interested in each other," the spy adds.

There’s more speculation going on here than in an episode of Gossip Girl!
