John Lennon is one of these celebrities that you didn’t know was adopted, but his adoptive parent was actually someone biologically related to him. After issues between his mother, Julia, and his father, Alfred, John Lennon was sent to live with his mother’s sister, Mimi. Lennon didn’t see his father for over 20 years after 1946 when his father wanted to secretly emigrate with John to New Zealand. When asked to choose between his mother and father, Lennon chose his father initially before following his mother.
