Hunger Games star Liam Hemsworth has revealed that he had to run out of his school sex education classes - because his mum Leonie was the teacher!
The actor told chat show host Jay Leno that despite having her son in lessons, his mum did not hold back, and taught the class the subject with graphic detail.
"It's exactly what you think it's like - really uncomfortable!" he said, as he recalled the lessons-from-hell.
"You're talking about chlamydia and STIs and every other sexually transmitted disease you can get."
"It was interesting until she starts talking about her own personal experiences," the 23-year-old added.
Liam, who split from Miley Cyrus last year, said that in the end he just could not take any more of his mum's teaching, and ran out of the lessons, telling his her: ''I'll see ya later, mum! I'll see ya at home!'.
Despite this, he still passed his exam on the subject.
"I think out of embarrassment she passed me, but I honestly got so uncomfortable I wouldn't turn up to most of her classes," he said.
"No child should have to be taught sex education by their mum!"
