Katy Perry sent her fans into a frenzy on Wednesday morning (March 4), when she teased her new "Never Worn White" video with a scene cradling a baby bump.The tune, unveiled at midnight on Thursday, has Perry taking a more emotional tone than her recent singles, musing over a piano melody.Directed by Paris pair J.A.C.K. (Madonna, Christine and the Queens), the video is equally ethereal with Perry looking like a queen in white.
