17. Pattie Mallette

Pattie Mallette, mother to the popular singer Justin Bieber, has reportedly claimed her virginity since giving birth to the singer.

“When you lose your purity at such a young age, you start think that you are not worth it. And when you lose your self-confidence, your self-identity, and your purity, you kind of attract what you believe you were,” Mallette said in an interview.

She’s known for taking that vow very seriously. “I wrote it down on a piece of paper, had somebody witness it. It means a lot, I made it this far, I’m not stopping now,” she said.
