The band announced on its website on Friday that its delayed sixth studio album will be released on September 25. No Doubt's last rendezvous behind the glass resulted in Rock Steady in 2001. "We are incredibly excited to share the new music with you. Ear candy coming your way!" the band wrote. "Thank you all so much for your support over the last 25 years. We'll be posting a lot of updates between now and September as we shoot the video and start rehearsing to perform the new songs live for all of you." It's hard to believe they've been together that long. Front woman Gwen Stefani doesn't look a day over 29.
