The Shout hitmaker, who was married to the late pop star for four years from 1969, reveals the 1970s icons taught her how to pen tracks.
She tells Britain's Attitude magazine, "I first got master classes in songwriting when I was married to Maurice - I used to sit and watch the Bee Gees write at home... So that's where I learned. I never wrote with Maurice, my brother did. I was slow, but I finally got there."
Gibb died in 2003.
