Keri Hilson Channels Diana Ross For Letterman

Singer Keri Hilson, whose song “Pretty Girl Rock” is constantly stuck in my head, stopped by David Letterman’s show last night to perform a more Motown-inspired version of the track, decked out in 60s attire that was reminiscent of Diana Ross and The Supremes. Or Dreamgirls, take your pick.
