Bruno Mars recently took to the stage at BBC Radio 1's 'Live Lounge' to deliver a perfect cover of Adele's 'All I Ask'.

The Grammy-winning singer performed the song he co-wrote with Adele, Philip Lawrence and Christopher Brody Brown, reports E! Online.

'All I Ask' is a piano ballad from the British songstress' third studio album '25.'

The 'Live Lounge' is a segment on the British radio station BBC Radio 1currently hosted by Clara Amfo. It exhibits well-known artists usually performing one song of their own and one by another artist, in an acoustic format.

Backed by a full band and two harmonizing singers, the 'It Will Rain' singer gave the song a dash of his signature cool with an electronic sound.

For the grand finale, Mars riffed impressively through a few key changes before landing on the final note.

"We love you, Adele!" he shouted before pushing over his stand for a necessary mic drop.
