The Long Island woman who poisoned a housemate by putting eye drops in his iced tea — a dirty trick depicted in the hit movie "Wedding Crashers" — was sentenced yesterday to three years' probation for the sickening assault.

Hairdresser Kristine Anzalone, 25, pleaded guilty to misdemeanor assault and was ordered by a Nassau County judge to pay her victim's $10,205 medical bill because he does not have health insurance.

Victim Joseph Gentissi Jr., 32, was not satisfied.

"It's not fair," said Gentissi, who had also accused Anzalone of killing his Chihuahua, Gucci.

"This is a woman who tried to poison me. She should have been charged with attempted murder. We were hoping she was going to get a strong sentence."

Anzalone's lawyer said her client was only protecting her unborn child, because Gentissi — who had lived with her and her then-husband, Christopher, in North Bellmore — refused to stop smoking around her while she was pregnant.

Anzalone yesterday declined to comment on the June 2006 poisoning, which caused Gentissi to vomit and bleed rectally.
