Bruno Mars talked during a radio interview about working with Adele on song "All I Ask" for her new album "25". He said, "She walks into the studio and 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.' "

Although his first impression on the "Rolling in the Deep" crooner was not really glowing, he soon found himself in awe of her talent. "Then, as soon as we hit a couple chords that she liked, we started rolling - and that's where we got that song from," he added.

"She's incredible. There was a moment when she was singing in the booth - 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," he continued gushing about Adele.

Witnessing Adele's tremendous skills at first hand, Mars eagerly said he would jump at the chance to perform "All I Ask" with the "Hello" hitmaker. "I don't know what she's waiting on, man. I'm like, 'Come on, Adele!' Like, send an email. Let me know!" he said.

He might next collaborate with Britney Spears. When he was told about Britney's desire to work with him, he readily replied, "Really? Right on, Britney. Come on, Britney! Come on down to the studio. Let's get it. Britney's an icon. I'd love to get in the studio with Britney one day."

Many stars are lining up to hit the studio with Bruno Mars as he becomes one of the most sought-after musicians in the industry, but Rihanna and Beyonce Knowles are the ones on his wish list. "I haven't done a song with Beyonce," he revealed.
