Jessica Sanchez as a diva? We'll need to see this to believe it.

And we soon will, the former American Idol finalist tells People, as Sanchez recently spilled the details regarding her upcoming guest appearance on Glee Season 4.

“I’m playing a student from a rival school who is supposed to be a legendary diva,” Sanchez tells the magazine. “A powerhouse singer.”

Okay. That we can believe.

Sanchez says she's especially excited to meet Naya Rivera ("She’s got that attitude and I love it.") and that she will appear on the final two episodes of the season.

Glee, meanwhile, is on hiatus and will return with new installments in April.
