Bruno Mars worked with Adele on her sweeping 25 anthem "All I Ask" — so it only makes sense that he's out here performing the track on BBC Radio 1's Live Lounge.

“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. Then, as soon as we hit a couple chords that she liked, we started rolling, and that’s where we got that song from," Mars recently said of his experience working with the "Rolling In The Deep" vocalist.

While in the Live Lounge studio, Mars also performed his brand new hit, "24K Magic" — which is exactly what he brought. Duh. It's Bruno, baby!

24K Magic will be released on November 18.
