PARK SLOPE — "Heroes" star Tawny Cypress lured her former husband to a Brooklyn burger joint, where her new spouse served up a whopper of a beatdown and then got the ex jailed, a new lawsuit charges.

The actress is accused of baiting her ex, photo agent Bill Charles, into going to Cheeburger Cheeburger in Park Slope on June 6 to see their son. Charles, 58, claims when he arrived, Cypress's new beau, Tom Dillon, knocked him out with a "hard object."

Cops ultimately arrested Charles in the incident, but he's suing Cypress and Dillon, accusing them of assault, kidnapping and lying about what happened.

Cypress, 36, who was married to Charles from 2000 to 2004, allegedly instructed her son to arrange a meeting with his dad, who shares custody with Cypress, at the Seventh Avenue restaurant about 4 p.m.

The TV starlet "knew that [Dillon] would be lying in waiting," the lawsuit says.

Charles accuses Dillon of knocking him to the ground, fracturing his nose and giving him a concussion. But when cops showed up, Cypress and Dillon concocted a fabricated version, according to the lawsuit filed Dec. 17 in Brooklyn Supreme Court.

Charles was arrested and spent six days in jail, according to the lawsuit. Court records show that he was charged with four misdemeanors, including assault with intent to cause physical injuries and acting in a manner injurious to a child. He was released on his own recognizance, and his next court date is set for Jan. 23.

"The relatively minor charges against my client are merely a distraction of the serious charges of attempted murder and kidnapping that Thomas Dillon committed against my client," Charles' lawyer, Robert J. Feldman, said. "[Dillon] concocted this whole thing. He had his cabal call police first."

The lawyer added that Charles abided by the court-ordered visitation rights he has with his child when he went to Cheeburger Cheeburger.

Charles, whose Park Slope firm represents fashion photographers and photojournalists, declined to discuss details of the incident.

"The truth is in the filing," he told DNAinfo.com New York. "It's all there, as sad as it is."

His lawyer did not return a call for comment.

Cypress starred in the 2006 season of the superhero drama. She has also had roles on the TV shows "Rescue Me," "K-Ville" and "The Good Wife."

In December, her Facebook fan page said she was filming an episode of the modernized Sherlock Holmes show "Elementary."

Her agent did not immediately return a call and email for comment.
