No Doubt singer Gwen Stefani called into Z100 on Thursday (March 17) to chat with Cubby. Stefani called while rehearsing for ‘Saturday Night Live’, as she’s the musical guest this weekend. She talked about her previous visit along with No Doubt, and this time she’s doing it solo. Stefani isn’t in any skits, but she wants to focus on the music. She’ll be performing ‘Rich Girl’ with Eve and the third single, ‘Holla Back Girl’, which she’s real excited about releasing. They wrapped up with an update on her upcoming TV appearances. The interview has since been removed from z100.com.
