Alec Baldwin had an eventful court appearance today in New York, where he testified at the trial of a woman accused of stalking and harassing the actor.

The New York Daily News reports that Genevieve Sabourin, who is charged with 23 counts of harassment and one count of stalking, shouted at the actor as he testified, saying "Wow, you’re lying," and, "I can’t believe you’re doing that," after Baldwin testified that the two have never been lovers.

Sabourin was eventually hustled out of the courtroom by her attorney after being threatened with contempt of court by the judge, the story reports.

Baldwin reportedly dabbed at tears as he recounted how Sabourin showed up at his home on the same day he proposed to his wife, Hilaria.

"And when Baldwin again denied he and Sabourin were ever romantically involved, the furious French-Canadian yelled, ‘You have a scar!,’” the New York Daily News reports. "Then Sabourin pointed at her hip in an apparent attempt to convince everyone that she had the goods on Baldwin."

As an agitated Sabourin was being ushered out by her attorney, Todd Spodek, she reportedly screamed: “I gotta prove that I had a sexual relationship. I didn’t do anything wrong. He’s lying! He’s lying!”

Sabourin also took shots at Baldwin’s wife, Hilaria, after she took the stand.

Sabourin reportedly screamed at Hilaria: “I never spoke to you. You’re going to hell, Hilaria. You’re lying.”

"But Sabourin’s shrieking failed to rattle Hilaria," the story reports. "She calmly said her hubby put her on the phone with Sabourin once in a vain attempt to get her to stop calling."

According to the report, Hilaria testified: "She starts shrieking at me, ‘You b—h! You b—h! You b—h! You b—h!’ Over and over again. And I said, ‘Genevieve, this is not appropriate.’”

"Hilaria said Sabourin eventually started tweeting her from the handle @Scarfacemadam. Sabourin, according to Baldwin, was the mistress of ‘Scarface’ producer Martin Bregman," the story reports.

Hilaria testified: "She started to write to me and tell me if I knew what was good for me to not show up to certain events."

The NY Daily News report adds: "Hilaria said Sabourin showed up unannounced at her husband’s East Hampton home after he got down on one knee and asked her to marry him. She said she finally sicced the cops on Sabourin on April 8 when she turned up at their E. 10th St. building and demanded to see Baldwin."

Said Hilaria, according to the report: "I was so afraid I couldn’t remember my address. I looked at a piece of mail. I was completely out of my mind."

The story adds: "Prosecutors contend Sabourin waged a months-long harassment campaign against the ’30 Rock’ star and bombarded him with 100 creepy emails and texts begging him to marrying her and ‘conceive a mini Baldwin.’”
