Yoko Ono – 88 years old
Yoko Ono may be best known for her multimedia art, in singing and songwriting mostly. Also, she’s famous for being John Lennon’s widow, but she is actually an accomplished singer artist in her own right. Despite inheriting John’s massive net worth, she still continues to create art and music and occasionally collaborates with other artists. Like the late John Lennon, Yoko is also a peace activist.
