Alicia Keys made a guest appearance on Late Night With David Letterman on Tuesday night where she talked to the host about her family and Christmas.

The singer then went on to set the Ed Sullivan Theater stage ‘On Fire’ with a soul-baring performance of her hit song on Tuesday night which brought the 2012 season of ‘Live On Letterman’ to a conclusion.

She opened the show with ‘New Day’, before going on to perform a reggae mash-up of her new track ‘Limitedless’, ‘You Don’t Know My Name’, her current track ‘ Girl On Fire’ and the epic ‘Empire State of Mind’, much to the crowd’s delight.

Alicia’s voice wasn’t the only thing to stand out.

The singer was dressed in a bright-yellow Marc Jacobs Resort 2013 ensemble with blue sequin stripes on both the crew-neck sweater and knit pencil skirt.

Vanity Fair’s best-dressed woman of the year followed the number one rule of wearing a crop top by wearing a high-waisted skirt to cover her stomach.

The look was completed with gold pointy pumps.
