Andy Kaufman died of AIDS and was bisexual! That and other senses-shattering revelations are detailed in a new book, “Andy Kaufman: The Truth, Finally,” by Andy’s BFF, Bob Zmuda, and his last girlfriend, Lynne Margulies.

“Andy’s secrets are finally being revealed now that his parents have died,” a publishing insider whispered to The 
National ENQUIRER.

Andy – best known as lovable goofball “Latka” on the TV hit sitcom “Taxi,” which ran from 1978 to 1983 – died of lung cancer on May 16, 1984 at age 35.

Yet Lynne is convinced Andy died of AIDS. She claims, “He was basically misdiagnosed. At that time AIDS wasn’t even known in America and it was before Rock Hudson was diagnosed with HIV.” She adds that Andy insisted they live in a sleazy part of San Francisco and he may have contracted HIV from gay sex in the seedy Castro District or with male hookers at the Mustang Ranch.

“The real reason Andy kept closeted about his bisexuality was not to protect his career, but he didn’t want his parents to know,” the insider said.

According to the tell-all, Andy also had an insatiable appetite for female hookers – seeing as many as eight a day!

“Andy didn’t like feminine, girly girls,” the insider disclosed. “He dug big, muscular girls who were equipped for wrestling. He was nuts about chicks who pumped iron!”

Co-author Bob believes Andy is still alive and faked his own death. He predicts one day the eccentric comic will return from the grave as per a “mondo bizarro” scheme that Andy used to confide in excruciating step-by-step detail.

First, Andy planned to “leak” to the media that he was cancer-stricken. To convince skeptics, he’d shave his head and become “scary skinny.”

A special-effects makeup artist would then construct a duplicate of Andy, placing the “clone” in his coffin.

“Scared witless, Bob begged Andy not to tell him anymore,” the insider divulged. Bob, co-producer of Andy biopic “Man On the Moon,” was also against Jim Carey playing Andy. Then he saw Jim eerily recreate Andy’s famed SNL sketch. Surprisingly, Garth Brooks was keen on playing Zmuda in the flick but his handlers said “no”.

“Bob really believes that Andy is still out there!”

He disappeared for two reasons – so he could enjoy his bisexual lifestyle in peace AND to pull off the greatest hoax in history!”
