AGNETHA FÄLTSKOG, 71 YEARS OLD

Agnetha Fältskog has found success all her life. After experiencing her first success in Sweden following her self-titled album in 1968, the now-71-year-old star gained international stardom when she joined the iconic pop group ABBA. Though the band officially broke up in 1982, it did not come as the end for Fältskog.

In fact, her newfound success came when she decided to go solo. She dropped three albums and did a movie. Mind you, the singer was the lead star of the film. However, despite the incredible degree of success she was experiencing, Fältskog decided to live in solitary in the 1990s. She avoided public life and lived on the island of Ekerö, but she again returned to the limelight in 2004 with a new album 16 years after being away. Fältskog also re-joined ABBA when it started performing once more.
