Tonight on the 55th Annual Grammy Awards, Alicia Keys and Maroon 5's Adam Levine performed a chemistry-filled mash-up of two of their hit songs.

Levine led the way, starting off with a chilled-rendition of 'Daylight' with the Maroon 5 band backing him.

Keys then heated things up a little, with her song 'Girl on Fire.' The chanteuse came out playing the drums instead of the piano -- her traditional instrument of choice.

Dressed in all-black, the singer eventually put down her drumsticks and walked a few steps over and joined Levine center stage to harmonize and carry out the rest of her chart-topping song.
