What did TV’s reigning diva have to say about pop princess Britney Spears?

Glee’s Lea Michele shared a few set secrets, along with her personal thoughts on the upcoming Britney-Brittany episode.

“She was so professional,” Michele said of Spears, who will appear in multiple scenes on the second episode of the second season of Glee.

“She was great to work with. It was one of those things where you go to work and you’re like, ‘I can’t believe we’re doing this!’”

Lea Michele also revealed a few tidbits about what fans can hope to see in the episode.

“We are in a scene together,” she admitted. “What we do together, I can’t say, but I will tell you it’s incredibly ironic! I can’t believe Ryan [Murphy] got her to do this.”

Sounds intriguing!
