Demi Moore at Daughter Tallulah's Graduation, Looks Slim and Healthy (PHOTO)

Demi Moore attended her 18 year-old daughter Talluah's graduation over the weekend; a rare appearance for the star since the actress' split from fellow actor Ashton Kutcher.

Demi Moore reunited with Bruce Willis for a day for the graduation, and reports stated that the actress sported a healthy and slim figure in a black dress and flats. The event was a complete family reunion as the couple's other daughters, Rumer, 23, and Scout, 20, also attended the event.

Scout, an aspiring singer who is currently studying at Brown University, was recently arrested for underage drinking and having an unopened bottle of liquor on the street.

Ashton Kutcher, who is reportedly still close to his step daughters, did not attend the event, despite rumors of a possible reuniting between the actor and Moore.

Moore has been recovering well say sources, since her recent stint in rehab, which followed the news of the actress' split from Kutcher. She was spotted last week in Los Angeles at the RockSugar Pan Asian Kitchen alongside friends.

"The entire group [seemed] in high spirits, laughing and appearing to enjoy their night out," an onlooker told People magazine.

While Moore was in rehab, Talluah spent time with Willis and her step-mother Emma Hemming. Talluah turned 18 in February, and has been spending the most recent months cuddling up to her boyfriend, skater Lucas Vercetti.

Reports stated that Talluah had at first struggled with her mother's health issues.

"She loves her mother and wants her to get help," but had been "mortified by her wild partying," a source told In Touch magazine.

Moore met Willis, her second husband, in 1987. The couple divorced in 2000 and in 2005 Moore married Ashton Kutcher before their split in 2011.
