Bruno Mars may be gearing up to release his upcoming album, 24K Magic. However, when he stopped by 103.5 KTU's Cubby and Carolina in the Morning, they couldn't help but ask Bruno about his collaboration with the one and only Adele. He co-wrote the achingly beautiful "All I Ask." 

While he revealed that Adele was "incredible," Bruno did say that the collab took some time to get right.

He explained, "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.....' And then as soon as we uh hit a couple chords that she liked, we started rolling, and that's where we got that song from." 

Either way, they did put a great song together, which Bruno is more than happy to perform with her one day. "I don't know what she's waiting on man, I'm like come on Adele," he said, "like send an email, let me know!"
