Lady Gaga checked asked Julie Andrews permission before performing at the Oscars.
The 'Do What U Want' hitmaker sung a medley of tracks from the 'The Sound of Music' - made famous by the legendary actress - at last month's Academy Awards ceremony and called the 79-year-old star to check she wasn't "offended" by her choice to sing hits from the musical.
She said: "She called me about 10 days before and she said, 'I just want to talk to you and make sure I don't offend. That what I'm doing is okay with you.' It was very generous of her.
"She said she'd been working so hard and she was singing everything in my keys. I said, 'Why? They're very high, even for me.' And she said, 'Because I wanted to honour you, so I did them in your keys.' That seemed like going one step beyond any place she needed to go."
Julie - who starred in the 1965 hit film - was incredibly impressed by the 28-year-old singer's performance, insisting she "hit it out of the ballpark".
She told PEOPLE magazine: "She hit it out of the ballpark. And then she was gracious enough to hand it to me. So that's a really wonderful thing to do too I think.
"As they say in Hollywood jargon, 'She rates tall in my book."
