Disney Channel darling, Demi Lovato, is the latest kid to enter rehab. Apparently Ms. Lovato has been severely depressed, cutting herself and alleged experimenting with cocaine. Recently, she punched another entertainer in the face in an unprovoked incident. It seems that kids that are pushed into the business at such a young age can't handle the fame and it doesn't appear that anyone is looking out for their best interests. How out of control should these entertainers be before their parents put their feet down and say, 'enough is enough!' ?
