Genevieve Sabourin is on trial for stalking Alec Baldwin, and emotions are running high with the notoriously mercurial actor who took the stand today.
Even before he walked in the door, Baldwin fumed at New York Post photographer G.N. Miller, shouting "Liar!" as he made his way into courthouse.
In February, Baldwin launched into a racial tirade against Miller, and his latest interaction with Miller was captured by video cameras this morning.
Things were less heated, but no less intense, after that.
The 55-year-old was arriving for the trial in Manhattan with Sabourin, who is accused of stalking the 30 Rock actor, is on trial for criminal harassment.
An emotional Alec testified that he never had a sexual or romantic relationship with the Canadian actress, wiping his eyes and trying to stay composed.
He said that after they met, she began leaving dozens of voicemails for him a night and eventually started threatening to show up at his homes.
Baldwin shared a meal with her at a friend's request, gave her an email address and phone number and communicated with her about acting classes.
That's when she began to barrage him with as many as 30 voicemails per night and hundreds of emails that started out as lovelorn and pleading.
They escalated into ominous threats to insinuate herself into his now-wife's yoga class and to come to his homes, even as he implored her to stop.
"It was nightmarish," he said, while Sabourin, who claims they had a tryst in 2010, had some outbursts as he testified, including: "You're lying!"
Her lawyer, Todd Spodek, has claimed in her defense that Sabourin wasn't stalking the actor, just seeking closure after he stopped talking to her.
Baldwin and Sabourin, who has appeared in Canadian films and shows, met during 2002's The Adventures of Pluto Nash, in which he made a cameo.
