She, of course, was more than all right.
"We made complete fools of ourselves afterward," she said, of the celebrating she and Wolfe, who joined her for the final part of the tryout, did. "I was so excited to call my parents."
Wolfe said she too got caught up in the thrill of it.
"It's 100 percent emotion when they come out with that golden ticket," said Wolfe.
Eventually, that emotion would take Sgambelluri from the audition room to jumping in a fountain outside the arena " a clip of which made it on TV during the airing of the Memphis episode.
Out of the 16,000 people who showed up in Memphis, 17 made it to the next level.
So far, Sgambelluri's preliminary audition hasn't aired, but she said it's possible it might show up on the "Rest of the Best" episode on Feb. 7.
In November, Sgambelluri joined more than 100 other contestants in Hollywood to begin filming the show's Hollywood round, where the field of contestants was narrowed to 24. Sgambelluri knows where she stands, but she's not allowed to talk about it.
"They pretty much own me for a while," said Sgambelluri, referring to contracts that contestants are required to sign that prevent from things like public performances and speaking about the results before the show airs.
Not that people don't try to get that information out of her.
"I have a lot of people taking me to the side, saying 'You can trust me,'" said Sgambelluri. So far, she's kept her mouth shut, just as she did until the results of the Memphis auditions were announced.
Not that it kept people from talking.
Sgambelluri said people would come up to her and say, "I heard Simon said you were horrible," and other rumors and speculation.
All of this made the end result more sweet, she said, when rumors were put to rest by the shot of her in the fountain, celebrating with her golden ticket.
This time around, she will need to carry the secret with her until the finalists are announced Feb. 15. Only she knows if she's going to need to book a plane ticket back to Hollywood.
