Lea Michele may be a good singer, and she may look a lot like Idina Menzel, but that does not mean she's confident about stepping into the Broadway star's shoes.

In an interview with Jimmy Kimmel, Lea admitted that she was nervous about singing the popular song from Disney's favorite, "Frozen" especially since she had big shoes to fill, with Idina's and Demi Lovato's renditions being as they are.

She told Jimmy on Wednesday, "I was super nervous. The day didn't start off so well. 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."

To make things worse, Lea shared that the crew also caught it on film and in slow motion, to which Jimmy pointed out, will be a good DVD extra.

Vomiting to one of the top songs of last year was a low point for the actress, but fortunately, some kids made it better later on. Lea said, "The rest of the day was great. Some of our crew members brought their kids and I was like, Oh this is so great."

Despite throwing up on set, New York Daily News said that the children on set that day were convinced that she is Queen Elsa, which excited the actress. She said, "It was awesome. I was like, 'I am god right now. I am a Disney princess god!"

She also got a boost of confidence from the original singer, Idina, who played the role of Lea's biological mother in the musical series "Glee". Idina sent Lea a goodluck message via Twitter.

And Idina went full on the support of the final product. Lea shared how nervous she was though, telling Jimmy, "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. We were sort of tweeting each other, and she knew it was happening."

All's well that ends well for the actress, but while she's been talking on Jimmy Kimmel live, there is another thing about the actress that grabbed audience attention. Inquisitr noted that Lea was wearing a ring on her left finger on her way to Kimmel, and it sparked rumors of engagement with her boyfriend, Matthew Paetz.

However, it was later revealed that it is nothing more than a promotion for her friend, Jennifer Meyer Maguire, who happens to be a designer: Maguire posted a photo of Lea modeling the lovely ring on Instagram.
