Did you know John Lennon co-wrote one of his biggest hits?
Bowie's left pupil is permanently dilated after being punched in the eye by his friend George Underwood (they were fighting over a girl).
Despite the fight, George and Bowie remain life-long friends.
George also did the album cover artwork for Hunky Dory and Ziggy Stardust.
