Who says pop stars aren't like the rest of us? When they want to get together to hang out and create best-selling songs, they don't pick up the phone, they text each other.
"I texted her, which is so cool. I can text Madonna!" Grande said. "Within a couple of minutes, she replied. She was like, 'Send me everything!'"
In August, Grande told Jimmy Fallon on The Tonight Show why it was important for Madge to participate in the project.
"Without Madonna, I wouldn't be able to make a song like that," Grande said. "She paved the way for all of us and has been here fighting that fight way longer than any of us."
Good thing Madonna didn't leave Grande on read.
