Jessica Sanchez goes from 'American Idol' to 'Glee'

It's official: "American Idol" runner-up Jessica Sanchez has signed a deal to appear on "Glee" Season 4. Who will she play? How long will she stay?

Zap2it has confirmed that Sanchez will appear on the show, though no details about her character or the length of her arc are known. TVLine first reported the news.

Executive producer Ryan Murphy tossed an interesting idea out on Twitter after the casting broke. "Michael Ausiello broke news of Jessica Sanchez on Glee. With voices like Jessica, Lea, Naya, Melissa, Amber, and Jenna...Streisand episode?"

There's no doubt those ladies are all capable of belting out Barbra, but Sanchez has such a great modern vibe -- it would be nice to embrace her youth, especially since she's only 17 years old.
