'Glee' Guest Darren Criss Hits #1 With 'Teenage Dream'

Katy Perry loves rendition, the first 'Glee' single to top digital sales chart.

Don't pinch yourself, because this isn't a dream: With 214,000 tracks sold, "Glee" guest star Darren Criss has scored a #1 hit with his rendition of [artist id="3274550"]Katy Perry's[/artist] "Teenage Dream," which debuted at the top of the digital sales chart this week — the first "Glee" single to do so, according to a joint statement from Fox and Columbia Records.

The tune debuted during "Glee's" November 9 episode, "Never Been Kissed," in which Criss made his first appearance as an openly gay teen from rival glee club the Dalton Academy Warblers. Criss is accompanied on the track by the Tufts University Beelzebubs, who also did the arrangement.

Criss is humble about the track's success, giving credit to great collaborators and good timing.

"There's a couple of things that stack up in my favor, preceding any shenanigans I may or may not be adding to it," Criss told MTV News.

"First of all, it's a great song ... between Dr. Luke, Ben Levin, Bonnie McKee, Max Martin, Katy Perry — those are all pretty strong pop writers. A lot of props go to the Beelzebubs from Tufts University, who arranged the killer arrangement. And the song was attached to a new character that a lot of people had a lot of speculation about. I'm just the lucky guy that got to be sprinkled on top."

Perry, however, couldn't sing Criss' praise more loudly, telling Access Hollywood, "He's amazing! I love when any of my songs are remixed or interpreted differently. I just I love that. I really welcome a creative mind to anything." The singer had previously tweeted, "Oh...My...Gosh... this just brought a sweet tear to my eye! Teenage Dream on GLEE makes my heart go WEEEEE!"

Criss said the feeling is mutual. "She's been really sweet. Katy makes my heart 'go weeeee.' It's a great tune. I really lucked out that I got to sing that song. I mean, you've gotta sing what they give you."
