Thanks to former Pussycat Dolls member Kasey Campbell for sharing a Throwback Thursday photo of herself, fellow Pussycat Dolls member Carmit Banchar and Dolls founder Robin Antin backstage with Gwen during The Singles Tour in 2004. As fans may recall, The Pussycat Dolls joined No Doubt onstage for ”Bathwater” during that tour.
