Demi Lovato returns to work; Not with Disney

demi-lovato-getty.jpgDemi Lovato is putting her nose back to the grindstone, but sorry "Sonny with a Chance" fans, it doesn't look like the starlet has returned to Disney just yet.

"Demi's management will inform us when she is ready to return to work," a Disney rep tells E! News. "As you know, last November, we announced hat we would focus on our 'So Random' sketch comedy show (the show within 'Sonny With a Chance') to keep the staff, cast and crew employed. We began production in January and will debut those episodes this spring."

So what is Lovato tweeting about, then?

"First day back to working," she posted Tuesday morning (Mar. 22). "I can't wait to share with you guys what I'm doing today.. It's a big day for me.. So excited! I love you all!!!"

If the use of exclamation points is any indicator -- the girl's got something big!!! going on.

What could it be? We're guessing the project is music related (though it could technically be a movie, as well). Maybe that Timbaland duet is coming to fruition?  Neither Lovato, nor her management are speaking up just yet.
