It is one of the world's most famous musicals.
But Michelle Williams seemed to have passed the challenge of her first ever night on Broadway with flying colours as she took a bow at the end of her performance of Cabaret. The blonde wore a look of smug satisfaction as she addressed the crowd at the end of her thrilling performance.
The Oscar nominated actress hardly took on an easy role for her big debut either, as she is playing lead character Sally Bowles, the role made famous by Liza Minelli in the 1972 movie version.

It was no mean feat, for the the 33-year-old had to roll back the years to play a character who is 14 years younger on the stage.
Luckily she had big name assistance to help her through, as flamboyant Scots heartthrob Alan Cumming was returning to the production as the Emcee character.
I'm so ridiculously excited to see this. Has anyone seen this already or have plans to? I'll be there April 16!
