But the replacement ain't too hard on the eyes: It's Adam Levine!
The Maroon 5 frontman (decked out in slick black slacks and black shirt) took to the stage with his band to perform "Daylight" before Alicia Keys joined them and the duo launched into a duet of "Girl on Fire." With Alicia killing it on the drums.
Then, they brought it back around and harmonized on "Daylight" again. And ended it with some more "Girl on Fire."
And it was amazing, right?
