Leif Garrett – Age 59

Leif Garrett rose to fame as a child actor turned ’70s teen idol. He shared the screen with his sister in several acting jobs, including Devil Times Five. He crossed over to music in 1976 when he signed a five-album deal with Atlantic Records.

He’s now 59 and barely looks like the teen heartthrob who gave us hits like I Was Made for Dancin’. Naturally, the Hollywood, California-native gained a bit of weight and has aged with time. In 2019, he published Idol Truth: A Memoir. Garett also made an appearance on The Dr. Oz Show in the same year.
