Lea Michele "let it go" alright.
The Glee gal confessed on Wednesday's"Jimmy Kimmel Live" that while performing the "Frozen" hit "Let It Go" on Fox's musical show, she threw up!
"I was super nervous. The day didn't start off so well," she admitted. "I was singing, there was snow falling, I looked up, trying to make it magical and beautiful, and ended up choking on the snow and vomiting on the ground. And they have it in slow-mo, on film."
Kimmel was quick to point out how great it would be to see that on the DVD extras. Despite puking during her performance, the final product got the approval of Princess Elsa herself, Idina Menzel (who plays Michele's biological mom on "Glee").
"At first I was sort of worried, because Idina sang it and Demi [Lovato] sang it...you know, so many people have done it. But I got Idina's blessing, which was wonderful," she revealed. "We were sort of tweeting each other, and she knew it was happening."
Following her embarrassing moment, the 28-year-old got another surprise when some of the crew members brought their kids to set and thought Michele was the real-life Elsa. "I realized, I turned to their parents, and I was like, 'Oh, they think I'm her,'" she recalled. "And then it was awesome. I was like, 'I am god right now. I am a Disney princess god!'"
