After a troubling nine months that has included a marriage bust-up, a stint in rehab, and the arrest of one of her children, Demi Moore looked rail thin and gaunt when she attended 18-year-old daughter Tallulah's high school graduation on Thursday.
The 49-year-old mom-of-three was dressed in a short black shift dress and ballet pumps that did nothing to hide how thin her arms and legs are.
The Striptease star was joined for the special occasion by ex-husband, Bruce Willis, and their older daughters, Rumer, 23, and Scout, 20, who were all excited to see the baby of the family graduate.
Noticeably absent was the girls' stepdad, Ashton Kutcher, who was once so close to the trio but has been estranged from them since his high profile split from Demi last September.
The graduation celebration came just days after Scout was arrested for underage drinking in New York.
