WOW! Want to know something really interesting?  Through google, I got to see Demi Lovato's old official website which is now "under construction" (demilovato.com) and in her news/schedule section, This is written:

"Demi’s also excited for her sister, Dallas Lovato, who just booked a role on Disney Channel’s latest pilot, “The Amazing O’Malleys”.  Directed by Fred Savage, it stars David Henrie, Selena Gomez (“She is one of my best friends – we were on the Barney and Friends show together when we were little.”), Jennifer Stone (“She is also one of my best friends.”), and Brandon Smith.  “We’re crossing our fingers that “The Amazing O’Malleys” gets picked up by the Disney Channel – Dallas has worked really hard for this, and we’re all very proud of her!”

Does that cast sound familiar?  uh, DUH! Wizards of Waverly Place!  Hmm, Dallas Lovato didn't make the cut I guess? Maybe not.  Who Knows?
