NEW YORK -- Jenny McCarthy worried about finding a good man after her son, Evan, was diagnosed with autism two years ago. Then Jim Carrey came along. "Beyond doubt it was written in the stars that Jim and Evan were a pair," the 34-year-old actress tells People magazine in its Oct. 1 issue.
"He's actually helped Evan get past some obstacles I couldn't. I sometimes call him the autism whisperer. He speaks a language Evan understands, and Evan feels safe with him."
McCarthy and Carrey, 45, went public with their romance last year. Though she's in love, McCarthy has no plans to marry the twice-divorced actor.
"There will be no certificate," she says. "It goes far deeper than that. Jim came into our life with an open heart and open arms. He's learned a lot about autism. He listens. The power of listening. It can move mountains."
McCarthy and film director John Asher filed for divorce in August 2005, after six years of marriage. Earlier that year, Evan, now 5, was diagnosed with autism.
McCarthy, who starred on MTV's "Singled Out," details Evan's progress in her new book, "Louder Than Words: A Mother's Journey in Healing Autism."
She says Carrey was curious about Evan — in a good way. But she was nervous about introducing them.
"He was intrigued," she says. "He asked questions. Still, it took me about a few months to bring Evan over."
Jenny McCarthy vividly remembers the harrowing realization three years ago that her son Evan, now 5, was autistic.
"It started with hand flapping," McCarthy, 34, told Oprah Winfrey on Tuesday's show. There were other telltale indications in her child's behavior, but as McCarthy said, "You only look for the good signs."
Then came the day when Evan suffered a seizure, which doctors – once she got him to the hospital – blamed on a fever. Three weeks later, however, Evan got "a stoned look on his face" while McCarthy and the boy were visiting her parents.
This was another seizure, she thought, "but this one is different. He's not convulsing." Instead, "foam was coming out of his mouth, (and) and after a few minutes, I felt his heart stop," she said.
When the paramedics arrived, she told them about Evan's heart. "They looked at me like I was crazy. I don't know why," she said. Only, as they discovered for themselves, the child's heart was no longer beating, so they administered CPR.
"Why, God? Why me ... Why? Why? Why?" McCarthy recalled thinking in those desperate moments, but then, she said, an inner voice came over her. "Everything's going to come out okay."
Because there was no pediatric hospital near her parents' home, Evan and McCarthy drove three hours back to Los Angeles, during which time Evan suffered several more seizures.
Initially, neurologists believed Evan had epilepsy, by McCarthy's "mommy instinct," as she called it, thought that not to be the case. Finally, a doctor said to her, "'I'm sorry, but your son has autism.' My mommy instinct said, 'This man is right.' I didn't want to believe him ... but ... this man is right. I felt like death."
McCarthy, however, sprung into action. She researched autism on the Internet and was struck by a message that popped up in a corner of the screen. Autism, it told her, "is reversible and treatable."
She worked diligently with her son, putting him on a wheat-free, dairy-free and artificial-additive-free diet to detox his system, and her mantra – which she says is producing results – is "hope, faith, recovery."
McCarthy, who first revealed Evan's condition last May on The View, has put her experiences down in a just-published book, Louder Than Words: A Mother's Journey in Healing Autism.
Evan is McCarthy's son with director John Asher. The couple divorced in 2005, after six years of marriage – which, McCarthy told Winfrey, was strained because of their son's condition.
But, McCarthy also said, there's a new man in her life: Jim Carrey. "He's the 'funny, cute guy' in the book," she told Winfrey and the TV audience. And, she stressed, he is there for Evan.

"Keep going," said McCarthy as final advice to parents of autistic children. "And we're going to be there online."
