Glee has gone global. The cast of the hit FOX show performed Journey's "Don't Stop Believing" on Britain's singing competition, The X-Factor, on Sunday.

Most of the cast performed, including Amber Riley, who plays Mercedes on the show and serenaded X-Factor judge Simon Cowell. Chris Colfer, who plays Kurt and was nominated for an Emmy for his role, did not participate, as he was still filming scenes for the show. "I had to stay and film scenes with the Warblers. Lot's of cool stuff coming up!" the actor posted on Twitter on Friday. "I expect my costars to bring me back enough 'William & Kate' merchandise to fill a small house."

Colfer will join the cast this summer for the GLEE LIVE! tour in Europe, which will hit London, Dublin and Manchester, from June 22-July 3. –ISHITA SINGH
