Letterman's Ladies: Katy Perry vs. Drew Barrymore

Star power was in full effect on The Late Show with David Letterman on Tuesday night, as the late night talk show host invited two sexy guests to share the spotlight. Katy Perry and Drew Barrymore were both dressed to impress, but only one of them shined the brightest!

Katy Perry showed off her flawless bod in a bright coral bandage mini, which featured crafty straps. The sassy songbird paired the attention grabbing number with Christian Louboutin Jeannette spiked sandals and oodles of colorful, tribal-inspired jewels.

Drew dazzled in a sequined copper top, which she paired with high-waisted, front pleated pants, the same Yves Saint Laurent Trib Two’s she wore to the Going the Distance premiere on Monday night and a Samantha Willis Bowery ring.
