Demi Moore has been dumped by her boytoy lover.

The 50-year-old actress enjoyed a brief fling with Vito Schnabel, 26, but the art dealer broke off their relationship after she flew to Miami to join him for Art Basel as he was worried the attention would distract from his career.

"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. He hated having photographers follow him around after work got out about him and Demi," a source told Page Six.

Vito, 26, was also said to be unhappy that Demi just wanted to party at the prestigious art fair as he was trying to work. "He 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 didn't need while all the big collectors were in town," the insider added.
