Demi Moore has been dumped by her latest toyboy. 

The 50-year-old star was reportedly told by Vito Schnabel that their brief affair was over when they met up at the Art Basel event in Miami. The actress was spotted in the Florida city yesterday looking downcast as she emerged from Starbucks in a blue shirt, which was unbuttoned to reveal her clevage, tiny denim cut-offs and dark sunglasses. 

Moore and art dealer Schnabel, 26, were an item for several weeks prior to their jetting to Florida for the annual art fair. Schnabel was reportedly angry that Moore turned up in Miami to party with other celebrities - and told her he wanted to end the relationship.

The Ghost star was later photographed acting bizarrely at a party with singer Lenny Kravitz and is said to have spent the weekend club hopping. After making "the rounds" at other Miami hotspots (including Le Baron at Nikki Beach), Moore and her posse arrived at the club Rec Room around 4 a.m., the source reveals, where they took a table toward the back and ordered "a bunch of beer." Demi reportedly showed up with a stray kitten she had found earlier in the day, only to ditch it during the party, allowing it to become a stray once again.

Schnabel is said to have been angry that Moore's antics meant he would not be taken seriously in the art world. '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 New York Post's Page Six. '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.'

Moore, who spent time in rehab after her six year marriage to Ashton Kutcher broke up earlier this year, met Schnabel at Naomi Campbell's party for her Russian boyfriend last month.

A spokesman for Moore has refused to comment.
