Darren Criss Learns 'How To Succeed'

Darren Criss doesn't know how to stop. With only about two more weeks left of filming Glee, he is gearing up to begin a three-week training course to replace Daniel Radcliffe in Broadway's How To Succeed In Business Without Really Trying. Somehow, his busy schedule still leaves time for charitable causes — and stalking Lady Gaga?

Backstage at the "A Night of Firsts" Miss Golden Globe announcement party in Hollywood Thursday night, Criss admitted to loitering around to try to catch a glimpse of Gaga, who was in attendance to accept the Trevor Hero Award for her work supporting gay youth. "Myself, Amy Adams and Rashida (Jones), a bunch of us were sitting like 12-year-old girls, because we knew Stefani Germanotta, Lady Gaga, was going to walk in," Criss told Billboard.com. "We all just kind of casually played it off like we weren't waiting, but then we all said to each other, 'we're all waiting because Lady Gaga is coming in here, right?'"

Criss said staring at the "Born This Way" star left him speechless. "We just kind of gawked in silent wonderment," he said. "She came in with her stilts and her crew of many, and we all had a really lovely moment together. It was like watching an eclipse."
