The upcoming series of teen drama Gossip Girl will see one of the male leads lock lips in a gay kiss.

The third series is currently in production in New York, and sources have revealed that Ed Westwick, who plays Chuck Bass, will have an encounter with a new gay character, university student Josh Ellis, played by Neal Bledose.

Gossip Girl has proved popular with gay fans on both sides of the Atlantic.

In 2008 Westwick’s decision to share an apartment with co-star Chace Crawford led to rumours about their relationship.

Gossip blogs Perez Hilton and Queerty.com claimed they had been contacted by reporters at NY Daily News and The New York Post claiming to have proof the heartthrobs were a couple.

Crawford’s publicist has issued a statement to Us Weekly confirming that he is “100 percent straight.”
