Pattie Mallette was just 17 when she gave birth to her son Justin, raising him as a single mother in Stratford, Ontario. She didn’t graduate high school, but a friend watched her son so she could return to get her diploma. After raising the boy in low-income housing on government assistance, his musical talent began to shine, and before too long he became known worldwide. Yes, that’s Justin Bieber. Mallette’s obviously wealthy off of her son, but her own book Nowhere But Up hit the New York Times best-seller list.
