Rocking a black dress with spaghetti straps, the Amazing Spider-man star stepped on stage at Studio 54 in New York City with the rest of the cast of the Broadway Revival production and waved to the audience.
Alan Cumming, Linda Emond and Danny Burstein were also beaming as they wrapped up their first performance with Emma, who was applauded by critics following her first night.
The 26-year-old actress was originally set to star as the lead role of Sally Bowles last spring, but Michelle Williams stepped into the role when Emma had to withdraw from the play due to scheduling conflicts.
After Emma landed the role, she told Jimmy Fallon on The Tonight Show Starring Jimmy Fallon she (sort of) already had a connection with one of her costars. "I saw [Cabaret] in New York for the first time with Alan as the Emcee when I was nine years old, which is the most inappropriate show to take a nine-year-old to," she said. "Do not bring a child!"
Nevertheless, Emma did admit she's been wanting to be in Cabaret since seeing it back then, adding, "You know, it's a strange part for a nine-year-old to want to play."
The production will run through March 29, 2015, with Emma performing her final show Feb. 1.
