NEW YORK (AP) — Alec Baldwin probably isn't relishing his part in this scene: a courtroom face-off with his accused stalker.
But it's likely to play out Tuesday in a New York City courtroom, where the former "30 Rock" star is expected to testify at the trial of Genevieve Sabourin, a Canadian actress.
Authorities say it's a case of an acquaintance with a movie star turning into harassment. Sabourin claims it was a romance that fell apart.
The Oscar-nominated Baldwin and Sabourin, who has appeared in Canadian movies and TV shows, met when he had a cameo and she was a publicist in the 2002 sci-fi comedy "The Adventures of Pluto Nash."
Fast-forward to April 2012, when Sabourin was arrested outside Baldwin's Manhattan apartment building.
The Manhattan district attorney's office says she had bombarded the actor with unwanted phone calls and messages professing her love, announced she was coming to New York and then showed up uninvited at his Manhattan and Hamptons homes, as well as a movie screening he was hosting.
Baldwin told police that he's had dinner with Sabourin but that their relationship was purely professional.
In the meantime, Baldwin got engaged to and married the former Hilaria Thomas in 2012, after they began dating the year before. They had a daughter, Carmen, this past August.
Hilaria Baldwin also is expected to testify.
Sabourin says she and Baldwin had a 2010 tryst and a two-way exchange of emails. Her lawyer, Todd Spodek, has said Sabourin wasn't stalking the actor, just seeking "closure" after he stopped talking to her.
Baldwin's career has included a Tony-nominated turn as Stanley Kowalski in "A Streetcar Named Desire" on Broadway, incarnating action hero Jack Ryan in the 1990 film "The Hunt for Red October" and an Academy Award nomination for his supporting role in the 2003 drama "The Cooler."
