Lea Michele revealed an interesting tidbit about her performance of Frozen’s “Let It Go” on the season premiere of Glee while on Jimmy Kimmel Live on Wednesday night.

Michele, who plays Rachel Berry on the hit Fox show, said she had some issues while filming the scene.

She admitted that even though she got Idina Menzel’s “blessing” to sing the song, she felt “a lot of pressure” trying to cover such a popular song.

“I was super nervous. The day didn't start off so well," she said, Us Weekly reports. "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."

Michele also talked about having a possible “breakdown” when they shoot the final episode of Glee, but she does already have a new gig lined up with Ryan Murphy’s Scream Queens.
