Demi Moore Is Single Again: Boyfriend Vito Schnabel Leaves Her And Moore's Daughters Question Her Hard-Partying, Sources Say

Demi Moore has allegedly been dumped by her latest boyfriend, 26-year-old Vito Schnabel.

According to the New York Post's Page Six, Schnabel, an art dealer, felt like Moore’s erratic behavior would undermine his career goals.

“Vito has worked very hard to be taken seriously in the art business and doesn't want to be seen as somebody who dates celebrities,” a source told the publication.

“He hated having photographers follow him around after word got out. Vito wasn't too happy that Demi flew down to party at Art Basel while he was working to build his business. It was a distraction he did not need while all the big collectors were in town.”

The Post reported that the couple had met in India during Vladimir Doronin's 50th birthday party thrown by his girlfriend, Naomi Campbell.

Last week, Moore attended a Chanel barbecue and auction at the Soho Beach House in Miami, and acted like a teenager, partying and dancing with other A-list celebrities such as Lenny Kravitz. Schnabel was in attendance and with Moore, but after the event, Schnabel told reporters in Miami that he and Moore weren't dating, according to E! News.

Schnabel is not the only one who seems bothered by Moore’s hard-partying. RadarOnline reports that her daughters, Rumer, Tallulah and Scout, are also concerned.

"[The girls] are mortified by their mother at the moment," a source told the site.

"They are becoming ever increasingly concerned about her bizarre and outlandish behavior. Demi just seems absolutely desperate for attention and they fear that she isn't in a good place mentally right now."

Moore was previously married to actor Ashton Kutcher, but broke up last year. Kutcher is dating his “That 70s Show” co-star, Mila Kunis. Though they have only been dating for seven months after knowing each other since 1998, “he [Kutcher] always had a thing for her," a source told Us Weekly. “It's a real infatuation.”

Esquire magazine recently gave the 29-year-old beauty the coveted honor of "Sexiest Woman Alive."
