She started dating the Give It Away singer when she was just 16 after they met through his bandmate Flea.

Skye, the daughter of Scottish folk singer-songwriter Donovan, claims then heroin-addicted Kiedis was a “pathological cheater.”

After she got pregnant, she claims he paid for the abortion at a Beverly Hills doctor’s office but refused to go in with her – “guiltily” dropping her off on the curb instead.

Skye writes, “Other people in our group had unsafe sex and they were fine, I kept telling myself, using my teenage reasoning.

“Of course, I could see how irresponsible we were being.

“Whether Anthony could see it too, he obviously wasn’t ready to grow up, to take care of himself and others, to make real adult choices.”

She added that she “was the type of girl who’d wanted a baby since I was a baby, who used to fantasize about finding a swaddled infant on my doorstep or catching a flying ghost baby with a butterfly net.

“But fantasizing was different from seeing. I couldn’t see having a baby at this point.

“I would not have a baby at 17, with someone who didn’t want to be a dad, wouldn’t commit to me and had anger issues,” she wrote.

“Not to mention the heroin.”

Before the pregnancy, Skye says in the book that she and Kiedis had an HIV scare due to having unprotected sex while he used needles to take heroin and allegedly cheated on her.

Skye says that after an agonising one-month wait for results, the couple were told that they were negative.

But her mother saw the needle mark from the test, asked if she was using heroin and was only part relieved to know it was from an HIV test.

“The whole time I was with Anthony, I think she was equal parts both— relieved I was still okay, and terrified I wouldn’t be,” Skye writes.

She also tells how she saw Kiedis shoot up heroin immediately after hearing about the death of his bandmate Hillel Slovak in 1988.

“I’m not in touch with him,” Skye told People on the book’s release, but said she felt nervous about what he would think of her decision to tell the world about their romance.

And she confesses that she was a “serial cheater” and a string of lesbian affairs while married to Beastie Boys rapper Adam “Ad-Rock” Horotvitz in the 1990s.

She writes that before her relationship with Horovitz, she cheated on every boy she had dated “all the way back to middle school.”

It included all four of her four serious boyfriends up to that point.
Skye blames “deep insecurity and need for validation” for her indiscretions.

Believing that her marriage to Horovitz would solve the problem, she finally realised the cheating was “never about my partners, it was about me.”

She tells how she would get lonely and anxious while Horovitz was on tour with his band and seek new conquests to comfort herself.

“I didn’t think of myself as a love or sex addict, but I did seek solace through love and sex,” she writes.

“And I did get a high from winning a girl over. At this point in my life, my drug was women.”

Skye explains that she had affairs with women including British musician Alice Temple, plus Madonna’s ex-lovers Ingrid Casares and model Jenny Shimizu, who also famously had a relationship Angelina Jolie.

Her marriage with Horovitz begin to break down when he came back to their Los Angeles home in January 1996 and found Skye in a pool with her lover Mai Lei.

She writes that after the couple “just retreated to different sides of the house, each of us processing, mourning.”

“I’d finally broken us,” she concludes.

Skye also details a fleeting romance with Matthew Perry after meeting with the Friends star on the set of teen comedy A Night in the Life of Jimmy Reardon.

Yet it was also 20 years later when she received an “out of the blue” call from Perry inviting her over.

“I only had to think about it for approximately fifteen seconds…I normally didn’t accept booty calls,” she writes, “which I assumed this was…but it was Matthew Perry!”

She went back one more time but said that was the last she ever saw him.

Skye previously told People that she was a “little nervous” over the details she was revealing in the new memoir.

“I definitely don’t want to hurt anyone,” she added.

“But some people I named in the book have read it, and luckily everyone has loved it.”
