"Hush Hush; Hush Hush" is a song by American female group The Pussycat Dolls from their final and second studio album, Doll Domination (2008). Written by Nicole Scherzinger, Andreas Romdhane, Josef Larossi, Ina Wroldsen, Dino Fekaris, Frederik Perren and produced by Quiz & LaRossi and Dave Audé for the remixed version, it was released as the album's sixth and final single on May 12, 2009. Lead and background vocals for both versions of the song are performed solely by lead singer Nicole Scherzinger. The release caused controversy as the single was credited as "Pussycat Dolls featuring Nicole Scherzinger" which caused tension within the group and rumored that Scherzinger would be going solo.
