Actress Genevieve Sabourin was found guilty Thursday on all counts of stalking actor Alec Baldwin.
Sabourin was sentenced to six months in jail on top of 30 days she already received for disrupting court proceedings.
Manhattan Criminal Court Judge Robert Mandelbaum said Sabourin was guilty of stalking, attempted aggravated harassment, harassment and attempted contempt of court.
Baldwin said Sabourin, 41, stalked him after he took her to dinner just to give her career advice. She says they had a fling that soured, and all she wanted afterward was an explanation.
The courtroom drama brought the Oscar-nominated Baldwin to the witness stand and sent Sabourin to jail for a series of outbursts. The judge declared her in contempt of court Wednesday and ordered her to spend 30 days behind bars.
Baldwin and Sabourin agree on this much: They met during a 2000 movie shoot in Montreal and had dinner a decade later in New York. The dinner came after mutual friend Martin Bregman, producer of movies including "Scarface," had Baldwin call her as she sought career help.
She says the dinner ended in a sexual encounter, which the actor denies.
He said Sabourin then besieged him with unwanted phone calls and emails. After a March 2012 message said she could infiltrate his apartment building and his now-wife's yoga class, "I knew that she was dangerous," the "30 Rock" star testified.
Then Sabourin showed up at a film screening he was hosting and at his Hamptons and Manhattan homes. She was arrested outside his apartment building in April 2012.
Sabourin, however, said the actor invited her to New York in 2010, took her on a dream date that ended in an amorous night filled with promises for the future, and then dropped her.
She said they maintained a fraught email and phone relationship over the next two years. While he did send some friendly emails, he says he also implored her to leave him alone.
She says the overall message from him was mixed, and she felt entitled to ask what had gone wrong.
"It's not because he's rich and famous that he can take advantage of women and throw them in the garbage," she said.
