Travolta revisits sad day

John Travolta said Wednesday he tried desperately to save the life of his autistic, seizure-prone son as he testified against two men accused of blackmail.

With his wife, Kelly Preston, looking on inside the Nassau courtroom, Travolta said he performed CPR on his son, Jett, after a nanny alerted him the teen had fallen ill at a vacation home on Grand Bahama island Jan. 2. Jett later died from a seizure.

“I ran downstairs with my wife to help my son,” Travolta said.

Paramedic Tarino Lightbourne and former Bahamian Sen. Pleasant Bridgewater are accused of trying to extort $25 million from the actor.

Apparently for the first time in public, Travolta said that 16-year-old Jett was autistic. The developmental disorder is often accompanied by seizures.

Travolta, 55, has kept a low profile since Jett’s death, skipping promotional events for his latest film, “The Taking of Pelham 1 2 3.”

Poor excuse for a papa

Former child star Mackenzie Phillips says in a new book that she had a sexual relationship with her late father, musician John Phillips of the Mamas and the Papas, that began with rape and later became “consensual.”

Phillips said on Wednesday’s Oprah Winfrey show that the relationship lasted for a decade until she got pregnant, and he paid for her to have an abortion.
