ELIZABETH TAYLOR’s son is considering pals’ suggestions that he write a “Mommie Dearest” tell-all that promises to rip the lid off of the movie legend’s worst perfor­mance – as a mother!

A book penned by Liz’s 59-year-old son Michael Wilding Jr. would be in the tradition of the scathing Joan Crawford biography and explain why Taylor, a beloved Hollywood icon, was no saint to her kids, say pals.

While Liz was known to be very generous with her time and money to charities, “she was never interested in her children,” a family insider told The ENQUIRER.

“Michael was overheard saying he would rather have grown up broke with a loving mother rather ‘than the way I was raised!’”

Wilding, a former soap opera actor, has been urged to write the explosive book with his wife Brooke Palance, daughter of the late movie star Jack Palance.

“It would portray Liz as an absentee mom, always away on movie sets, flying around the globe or in the arms of a man,” revealed a family friend.

Elizabeth’s four children were trotted out for photo opportunities to give the appearance of a loving, close-knit family, but the friend says: “That couldn’t be further from the truth.”

Michael, Liz’s son with second husband Michael Wilding Sr., spent much of his life “in a desperate bid for her attention,” according to the insider. “The book would talk about how Michael rebelled against his mother, running away to join a rock band, hanging around the drug scene and bedding a lot of women.”

During the mid-’70s, Michael lived on a farm commune in Wales, playing sax with a five-mem­ber rock group. He was married at 17 and had a daughter, but the union blew apart after just two years. He had another daughter with a girlfriend at the commune in 1975 but didn’t settle down until tying the knot with Brooke in 1982, and they had a son seven years later.

Despite Michael’s differences with his mother, he was the one who oversaw her care leading up to her death last year at age 79.

But now, said the friend: “Michael could spill all the family secrets as a way of coming to terms with a mother who was never there.”
