NEW YORK -- Before her trial even concluded, Alec Baldwin's accused stalker was ordered to jail for 30 days Wednesday after a series of courtroom outbursts got her declared in contempt of court.

After Genevieve Sabourin's days of sobs, gasps, remarks and interruptions continued during some legal arguments Wednesday, Manhattan Criminal Court Judge Robert Mandelbaum told her, "That's it." He found her in contempt and issued the punishment, which means she'll spend in jail while the trial continues.

Mandelbaum had warned Sabourin he might do so if she didn't stop speaking out during the proceedings. He's hearing the case without a jury.

Sabourin greeted the development with a soliloquy about the strain of the trial and the pain of hearing what she says are false allegations, calling herself "a person who is totally exhausted, humiliated, beat up, destroyed, alone."

"My life is shattered in pieces," Sabourin said.

Sabourin, 41, a Canadian publicist and actress, met Baldwin in 2000 during the filming of the sci-fi comedy "The Adventures of Pluto Nash." He had a cameo, and she was a publicist.

The two had dinner together in New York in 2010, both sides say.

Baldwin and prosecutors say she then conducted a campaign of harassment that escalated from phone calls and emails to showing up uninvited at his homes.

"It was nightmarish," Baldwin, 55, testified Tuesday. He likened the situation to an Alfred Hitchcock production.

Baldwin "became very flirtatious" at their first meeting in 2000 and invited her to visit him at his Hamptons home, Sabourin said as her testimony began Wednesday. She says the two had a sexual and romantic relationship, which Baldwin denied on the witness stand.

Meanwhile, another Hollywood figure became an issue in the case: "Scarface" and "Dog Day Afternoon" producer Martin Bregman, who was also a producer of "Pluto Nash."

Baldwin testified that Sabourin was Bregman's mistress and that Bregman asked the actor to give her advice. The married Bregman, however, later said by phone that he "never had an affair with her" and was shocked that Baldwin had said otherwise. Sabourin also says she and Bregman weren't romantically involved.

Bregman told The Associated Press on Tuesday he thought Baldwin had found Sabourin attractive, but "I don't know if anything happened between the two of them."

Prosecutors included Bregman on their list of potential witnesses but didn't call him because he told them "he had little to say about this incident," Manhattan Assistant District Attorney Zachary Stendig said Wednesday.

But Mandelbaum agreed to what's called a "missing witness" instruction, allowing him to infer that Bregman's testimony wouldn't have been favourable to the prosecution.

Bregman isn't expected to testify for the defence, either.
