Keri Hilson Channels the Supremes on 'Letterman'

We've already seen Keri Hilson pay tribute to one of her idols -- Diana Ross -- in the video for "Pretty Girl Rock," but Hilson decided to take it up a notch in channeling Miss Ross again when she performed the song on last night's (Jan. 4) "The Late Show with David Letterman."

Complete with two back-up singers -- or shall we say " Supremes" -- standing behind her and dressed a la 1960s Ms. Ross, Hilson recreated early Supremes' hand gestures while crooning the lead single off her new album, "No Boys Allowed."
