Julian Lennon: ~ $55 Million

Late Beatles star John Lennon’s first wife was Cynthia Lennon, but most people recognize his last wife, Yoko as his only wife. John and Cynthia had a son named Julian, who followed in his father’s footsteps and became a musician himself.

While he may have inherited the musical gene from his dad, John ensured that his “new” family of Yoko and their son Sean got the lion’s share of his estate after his death. Julian and his mom got next to nothing from his will. Still, Sean’s own talents makes him worth $55 million.
