Access Hollywood caught with Darren before his musical moment with Katy, where he spoke passionately about his "Glee" character, Blaine.

"It's high time for a character like Blaine on network television," Darren said. "It's really a wonderful thing that young people have someone to look to, who may not be able to identify with [Chris Colfer's character] or other out teens on television, if there are any other out teens on television?

"It's a real privilege for me, as far as just being able to speak directly to the things that I believe in, I'm very proud to be here," he added.

"Glee" fans can expect to see more of Darren live soon - he's hitting the road with the rest of the gang from the hit FOX series when they tour Europe in summer 2011.

"I am, I think so, I'm pretty sure I am," Darren said when asked about the tour.
