In the Andrew Lloyd Webber show, Scherzinger stars as Norma Desmond, which has already earned her an Olivier Award for her turn in the role on the West End. Scherzinger is already earning rave reviews for her Broadway debut -- and the actress even earned a six-minute standing ovation on her opening night.

Ahead of the night, she told Vogue that she prepares for the stage "like an Olympian."

"I'm very focused and have been working really hard, as has the whole cast," she said. "I've been extremely disciplined, watching and protecting my voice."

She spends her time before shows doing warmups, but when it comes to getting into character, her method is tightly guarded.
