Demi Moore used to grab headlines for her acting, now it’s for personal catastrophes or little things like deciding on a new name to tweet from. She has publicly moved on from former hubby, Ashton Kutcher, by dropping his name (@mrskutcher) as her Twitter handle. Although you know she wishes she could call herself Mrs. Kutcher again.She recently returned to the social networking site after a three month absence that included a stint in rehab for an assortment of problems including drug abuse and an eating disorder. Of course her official explanation for rehab was the blanket catch-all diagnosis, “exhaustion”. Mind you, who wouldn’t be exhausted after starving themselves, taking loads of recreational drugs, and trying to sleep with every young Hollywood hottie in pants?
