Hollaback Girl seems to have no doubt about what she wants to do next!
Gwen Stefani wants to team up with her old band No Doubt & work on another album.
Stefani just released her first solo album, which is really cool, but seems like she doesn't want to do another one!
She told MTV: "I don't think I will make another solo album. I can't predict anything. I definitely feel myself going back to No Doubt after this to do a new album."
Stefani clarifies: "I don't really know what will happen with those other songs. There's probably about 10 left over. I could make an album with them really fast."
