8. Leonardo DiCaprio

At the age of 16 Leonardo DiCaprio was already defining himself as a teen heartthrob when he appeared on Growing Pains between 1991 and 1992 in the recurring role of Luke Brower, a homeless teenager taken in by the Seaver family. His role came at the end of the series, right before his film career began to take off, but it was definitely clear, even in the early days of his career that he would make it big.

Thicke was only 12-years-old at the time. There’s even an interview of him at the age of 13 with his dad on the set of the show where he talks about one day becoming a musician.
