But if anyone is up to the task of doing justice to an incredible performance, it's Bruno Mars, who stopped by the BBC Radio 1 Live Lounge to cover Adele's "All I Ask" off her album, 25.

Mars and Adele actually collaborated on "All I Ask," and in his new cover story with Rolling Stone, he reveals that the two had a disagreement over the line, "Take me by the hand while we do what lovers do."

"We were aiming for that big, diva, ballad thing – that's what I envisioned," Mars explains. "But 'lovers'? I don't know if anybody really says 'lovers.' 'Yeah, we're lovers.' 'This is my lover.' I was like, 'Should we rethink that?'"

"But [Adele] was so gangster about it," he adds. "She was like, 'Nope. That's what it has to be.' And she was right. It's this grand word that makes the song bigger because no one says it. Because nobody talks like that, it pops out. It's not 'what boyfriends-and-girlfriends do' – it's this over-the-top 'lovers.' Sometimes I play it on the piano, and I look forward to singing that part. It's f**king perfect."

Mars is a huge admirer of the British singer, and told the Cubby & Carolina Bermudez In The Morning radio show last month that working with her gave the 31-year-old singer a chance to see Adele's magic up close.

"She's incredible," Mars shared. "There was a moment when she was singing in the booth -- and I'm not exaggerating at all -- 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."

Meanwhile, Mars -- whose third album 24K Magic is set to hit stores on Nov. 18 -- has been on a superstar streak of his own lately!
