Neither had publicly spoken about the telephone conversation they had after word spread that DeGeneres was a lesbian until Madonna recently taped an appearance on DeGeneres' show.
The chat aired on Monday (29Oct12).
Ellen said, "Before it was really official I was coming out... it was a big, huge topic... and I'd never had that much media attention; it was really scary for me... and Madonna called me outta the blue; we had never met.
"You said some really amazing things that I won't share because they were very personal about, like, holding on to this ride."
DeGeneres revealed the pop star also sent her a quote from dancer Martha Graham that inspired her to hold her head up high after the gay reveal hit the headlines.
She told Madonna, "It meant the world to me."
