Following the big news that Katherine Heigl won’t be returning to finish her stint on the hit show “Grey’s Anatomy,” it seems like ABC Studios is trying everything they can to keep its momentum up. According to reports, teen actress and Disney favorite Demi Lovato has been tapped to appear on an upcoming episode this season.

Zap2it is reporting that ABC has confirmed that Lovato will appear on “Grey’s Anatomy” during May sweeps (no surprise there). The teenager also went to her official Twitter page and announced the news herself.  She stated, “I’m so thrilled to announce that this week I’m shooting Grey’s Anatomy!!!!!!!! :D AHHH!!!!” Yeah, that sounds like a 17 year old’s response to me. Lots of exclamation points and smiley faces.

On another note, her character on the show might have some serious depth that we’ve never seen the actress take on before. She’ll star as a patient who may or may not have schizophrenia, which means she will have to go to some dark places to give a realistic performance. Lovato currently stars on the Disney series, “Sonny With a Chance,” and here she’ll have a real chance to tackle some meaty material.

What do you think about Demi Lovato guest starring on Grey’s Anatomy? Do you think she can pull off this type of role?
