Lea Michele may have let a little too much go when she sang rendition of "Let It Go" for an episode of "Glee" 

The 28-year-old sang the popular "Frozen" song on the Season 6 premiere of the musical series, and revealed on "Jimmy Kimmel Live" that she literally couldn't contain her excitement over performing the hit.

"At first I was sort of worried, because Idina [Menzel] 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 told Jimmy Kimmel.  

But getting the Broadway vets stamp of approval was the least of her worries.  

"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."

"That's going to be a great DVD extra," Kimmel joked.

Despite the incident, the raven-haired beauty's performance went over well ... so well that she was actually mistaken for "Frozen" character, Queen Elsa.  

"I realized, I turned to their parents, and I was like, 'Oh, they think I'm her,'" she laughed.  "And then it was awesome. I was like, 'I am god right now.  I am a Disney princess god!'"
