Adele didn't have Bruno Mars at "Hello." The "24K Magic" star recently opened up to the radio show "Cubby & Carolina Bermudez In The Morning" about working with the British Grammy winner on her song "All I Ask."
"She's incredible," Mars began. "There was a moment when she was singing in the booth, and I'm not exaggerating at all and the water was vibrating...like you know that scene in 'Jurassic Park.' She's got some pipes on her, and she's just a superstar."
But Mars admitted that he wasn't impressed with Adele from the beginning.
"She walks into the studio, she's got all this attitude, she's a diva, she's like, 'I don't want to do this. I don't like that,'" he recalled. "And then as soon as we hit a couple chords that she liked, we started rolling, and that's where we got that song from."
Despite a bad first impression, Mars said he'd love to perform the tune with Adele, saying, "I don't know what she's waiting on, man. I'm like come on Adele, like, send an email, let me know!"
The two-time Super Bowl halftime performer also gushed about Lady Gaga's upcoming performance in 2017.
"It's gonna be great," he said, even offering up some advice to the Mother Monster. "You gotta take it in. When you're up on that stage take it in because it's going to be over within 2 seconds."
