Demi Lovato Singer Demi Lovato arrives at the People's Choice Awards 2010 held at Nokia Theatre L.A. Live on January 6, 2010 in Los Angeles, California.

Just like fellow Disney starlet Miley Cyrus before her, Demi Lovato has decided to be the latest celebrity to walk away from social networking service, Twitter.
Demi was saddened to cancel a show, but apparently she had no control over that. When fans barraged her with messages, she couldn’t take it anymore.

We wonder who will be the next Twitter Quitter!
Any ideas?
