"She's incredible," he said. "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? The water starts jiggling. She's got some pipes on her and she's just a superstar."
And he said that he would love to work with her again. From the sound of it, he's just waiting for her "Hello."
"I don't know what she's waiting on man," he said. "I'm like, 'Come on, Adele. Like, send an email, let me know!"
Otherwise, Mars also said he was open to any number of other star-studded collaborations as well. At mention of Britney Spears once commenting that she would most like to work with Mars, the hit-maker replied that he'd be game.
"Come on Britney, come on down to the studio" he said. "Anybody who want to work, I'd love to see if there's anything I can contribute. Britney's an icon, you know."
Mars also named Beyonce and Rihanna as other artists he'd most love to partner up with in the studio. He added, "Anybody who want to work, come on down. It's a job fair!"
