Charlie Chaplin and his future wife Oona O'Neill (daughter of playwright Eugene O'Neill) first met when he was 53 and she was 17. He'd already been married three times, twice to 16-year-olds. O'Neill explained their relationship: he "made me mature, and I keep him young." Here are some couples who are making it work, at least for now, despite being at least 20 years apart in age.
1) Melanie Hamrick and Mick Jagger
The Rolling Stones co-founder, who is in his 70s, met ballerina Melanie Hamrick in 2014 and they started dating. In July 2016, the singer’s spokesperson confirmed that 29-year-old Hamrick is pregnant and the couple is expecting their baby in January 2017. The age gap between the couple is 43 years.
