VIDEO: Janelle Monae Kills It On "Letterman"

Janelle Monae hit up the Late Show With David Letterman last night to promote her new album The ArchAndroid. Monae, who’s about to hit the road with Erykah Badu and N.E.R.D., gave a rousing performance of “Tightrope” that saw her shuffle around, whip off her jacket and then finally don a robe, James Brown-style, while soulfully belting out the end of the song. Letterman even coaxed Diddy to come on stage when Monae finished (she’s signed to the rap mogul’s Bad Boy label).
