Pussycat Dolls founder Robin Antin has sued the outfit’s most prominent member, Nicole Scherzinger, accusing her of “extortion”. Antin says that Scherzinger is refusing to take part in a delayed reunion tour unless she is granted a larger share of its profits and “complete creative control”.Scherzinger agreed to take part in the tour in 2019, following two years of negotiations, says Antin’s lawsuit.
