Pussycat Dolls singer Nicole Scherzinger is to guest star in the comedy series 'How I Met Your Mother'.
Entertainment Weekly reports that the guest 'X Factor' judge and 'Dancing with the Stars' champion will play Robin Scherbatsky's (Cobie Smulders) former best friend Jessica Glitter.
The episode will focus on Robin's previous career as pop star Robin Sparkles.
"It’s going to be a satisfying third chapter in the Robin Sparkles trilogy," said executive producer Craig Thomas.
