Walsh-Smith lashes out against Smith in the tearful and furious YouTube video, which has attracted more than 3 million hits. She makes embarrassing claims about their intimate life and then calls his office to repeat those claims to a stunned assistant.

On the video, Walsh-Smith also goes through their wedding album, describing family members as "bad," "evil" or "nasty," and expresses concern about eviction from the couple's luxury apartment.

Judge Harold Beeler said on Monday that a prenuptial agreement signed three weeks before the couple's 1999 wedding was valid. This means Walsh-Smith must leave their posh Park Avenue apartment within 30 days and Smith, president of The Shubert Organization, the largest theatre owner on Broadway, must pay her USD 750,000.

Smith said after the ruling he was "sorry it had to come to this." "I'm happy with the decision of the judge, and I'm happy with the outcome," he said.

Walsh-Smith didn't see the decision the same way. "I think it's disgusting," she said. "I'm really, really disappointed with the decision."

She accused Smith of "basically throwing me out on the street." One of her attorneys, Joseph P McCaffrey, said they would appeal.
