Back in January, it was confirmed that 'Gossip Girl' star Chace Crawford had signed up to joined the cast of 'Glee' for its upcoming 100th episode and he has now opened up about the opportunity.

During a new interview with MTV News, the heartthrob explained that the character he will be playing is "douchey" in the way that he behaves and it made the scenes really fun to shoot:

"I play, like, her douchey boyfriend from, like, the Northeast, so it's more of a character, it was a good time. [I did], like, four or five scenes, we had a blast."

He went on to confess that while he was initially excited about joining the show for its 100th episode, he quickly became concerned about the musical aspect of the programme because he didn't want to sing:

"It was great, it's funny, I know like 80 percent of the cast already, [the show's creator] Ryan Murphy calls up and is like, 'come on,' you know, and [my first question was] 'do I have to sing?' I'm like, 'I'm not singing, I can't sing.' Anyway, I'm not singing."

Crawford also praised a member of the 'Glee' cast, Broadway actress and singer Kristin Chenoweth, adding that he thinks she's fantastic: "To be honest, I know, I know all of them, I did see Kristin Chenoweth (who plays April Rhodes), I love her, an Oklahoma girl, you know what I mean?"

He will play Quinn Fabray's (Diana Agron) new boyfriend, Biff, and the episode is due to air in the USA next month in March.
