An outraged judge slapped a Long Island woman with a jail sentence for trying to drive a wedge between her ex-husband and their daughters, keeping them apart for weeks at a time and even claiming he groped one of them.

Lauren Lippe is a vengeful roadblock, the barbed wire standing in the way of her two daughters and their desperate dad, Judge Robert Ross said.

Lippe often went nuclear, launching foul-mouthed tirades at Ted Rubin in front of the girls -- calling him a "deadbeat," "loser," "scumbag" and "f - - - ing asshole."

WIFE OF CRIME: Ted Rubin (above), with daughters Danielle (left) and Niki, was smeared and nearly kept from his kids by ex-wife Lauren Lippe (inset, at her Long Island home yesterday), a judge ruled.

Ross said Lippe, 47, was a scheming manipulator who deliberately planned last-minute trips and events when her ex was scheduled to visit the girls.

"He was compelled to consent or risk disappointing the girls," Ross wrote in his ruling, which found Lippe in contempt for violating the couple's joint custody agreement.

"We all hope you die from cancer," she once blared at him, the court papers said, with both daughters in her arms.

Lippe even had the nerve to smirk in court when an emotional Rubin described the agony of missing out on Hanukkah with his children. Ross said Rubin was relegated to visit at the end of his ex's driveway, where he lit a menorah with his daughters in his truck and watched them open presents from their grandparents.

But the worst, Ross wrote, was "the crescendo of the plaintiff's conduct" involving false accusations of sexual abuse.

Lippe charged in 2008 that Rubin had fondled the breasts of one of his daughters. Lippe later conceded that she knew nothing sexual had occurred.

"The evidence before me demonstrates a pattern of willful and calculated violations of the clear and express dictates of the parties' Stipulation of Settlement," Ross wrote in a decision handed down last week.

The judge was also annoyed that Lippe had punished the children for wanting to spend quality time with their dad.

On Thursday, Ross sentenced Lippe to six weekends in jail to be served on the first and third weekends of June, July and August. Lippe, who has since remarried, was scheduled to begin her jail time Friday, but her sentence was stayed pending an appeal. Rubin is expected to take care of the children while Lippe is on lockdown.

Lippe declined to comment outside her Lloyd Harbor home, but her lawyer, Kieth Rieger criticized the decision.

"It's extremely unusual, and in this case, it's inappropriate," Rieger said. "He chose to believe the husband and not her. Of course, she's upset, but she's also worried about her children. She's worried that if she goes to jail how it will affect the children."

Rubin, 52, a marketing executive, declined to comment, but has sounded off about his dilemma on his Internet blog.

"Spending time with my girls is something I put before all else," Rubin wrote last year. "They are teenagers now and being a divorced dad, it can be challenging to continue to reach out, put them first, and maintain this in the face of their occasional lack of interest and the roadblocks so easily put in place by their mom."
