Ladies, are you ready to do the “Pretty Girl Rock”? Keri Hilson takes a trip through the ages in the decade-spanning video for the newest single from her sophomore album No Boys Allowed (Dec. 21). Directed by Joseph Kahn, the clip puts Miss Keri in a handful of looks including a flapper girl in a silent movie and a Motown front woman, targeting specific singers by mimicking Janet Jackson circa “Rhythm Nation” era and T-Boz from TLC’s “Creep” video. Take a stroll down memory lane with the blonde bombshell.  Shout out to my chicas Christina "Pasty", @Bperryrussell, @AnnalisiaSimone, & Alex! Looking good!
