Artists Who Topped the Billboard Hot 100 Before They Turned 20
Michael Jackson: 11 (Jackson 5)
When the Jackson 5 released their first single "I Want You Back" in 1969, their label's marketing team tried to pass lead singer Michael off as two years younger than he actually was. Even so, he remains the youngest artist ever to chart a number 1 single on the Hot 100. Too bad it was at the expense of his childhood.
