A SLOW LEARNER

Mary Kay: Sex with 12-yr.-old is illegal?!

Disgraced teacher Mary Kay Letourneau, who served prison time for having sex with a 12year-old student she later married, insists she never knew her affair with a sixth-grade student was illegal.

“I’ve said this over and over again: Had I known, if anyone knows my personality. Just the idea, this would count as a crime,” she said on “Sunday Night” on Australia’s Channel Seven. “If someone had told me, if anyone had told me, there is a specific law that says this is a crime.”

The former Washington state teacher, now 56, pleaded guilty in 1997 to raping her 12-year-old student Vili Fualaau.

She was a 34-year-old married mother of four when their relationship began — but waved off the suggestion she should have known better.

“Who was the boss? Who was the boss back then?” Letourneau asked her boy-toy husband, now 35, suggesting that he pursued her, News.com.au reported.

“He did say he was in love with me,” she said. “I did the best I could.”

Letourneau (right, with Fualaau) has claimed her preteen student initiated the affair and aggressively pursued her.

She was out on parole six months after being convicted but was caught having sex with the teen in a car and sent back to the slammer.

By then she was pregnant with the couple’s second child, Georgia, 19, who was born behind bars. Their first child, Audrey, 21, was born shortly after Letourneau’s initial arrest.

The kids were raised by Fualaau’s mother until Letourneau’s release about seven years later.

The teacher-student pair married in 2005 and say they’re still madly in love, despite reported issues with their marriage. Last year, Fualaau filed for divorce but then withdrew the request.

“Anyone that’s married knows that it’s a labor in love,” Letourneau said.

They still live together and their daughters have recently moved out of the family home.

Their daughter Audrey said the relationship her parents have is “normal” to her and her sister.

“It’s kind of surprising to people but it’s normal for us because we’ve adapted to it,” she said.

Their dad, who is just 13 years older than Audrey, is more like a “friend-dad,” she conceded.

Letourneau is working as a paralegal these days and says she wants to use her newfound skills to scrub her name from the sex offenders’ registry.
