Gwen Stefani has appeared on Idol previously. She styled the season 10 contestants last year in her own L.A.M.B. line. That was the week Pia Toscano was eliminated, and there are those who blame Gwen’s fugly clothes for her shocking boot. Heh.
Gwen also mentored the Season 6 finalists in a Top 10 theme week that was “Insprired by the Songs of No Doubt”. One of Idols’s vaguest themes ever!
Of course, No doubt is signed to mentor, Jimmy Iovine’s Interscope Records.
