Lady Gaga Asked for Julie Andrews' Approval Prior to OSCAR Tribute

PEOPLE reports that Lady Gaga called SOUND OF MUSIC star Julie Andrews days before she was to perform her memorable tribute to the iconic film at the 87th Annual Academy Awards.

Andrews revealed to PEOPLE, "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 continues, "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 honor you, so I did them in your keys.' That seemed like going one step beyond any place she needed to go."

Andrews went on to praise the singer's performance, gushing, "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." She added, "As they say in Hollywood jargon, 'She rates tall in my book,' "

A special 50 Anniversary SOUND OF MUSIC DVD was released on Monday, March 9th.
