No Doubt promise their new album will be "ear candy."

The "Don't Speak" group are releasing their as-yet-untitled sixth album - their first for over a decade - on September 25, can't wait for fans to hear the results. "We are incredibly excited to share the new music with you. Ear candy coming your way! Thank you all so much for your support over the last 25 years. We're really proud of our new album and we hope you love it as much as we do. We'll send plenty of photos and webisodes as we go so you're there with us. See you soon," a post on their official website read.

The group - made up of Gwen Stefani, Tony Kanal, Adrian Young and Tom Dumont - have previously revealed working titles for tracks including "Party-Ready Reggae Blast," "Steady Down" and "One More Summer."

The group has been working on the record since the beginning of 2011, but Gwen admitted it takes them a long time to perfect their ideas.

"My band takes a weird process. It takes so long. We've been doing a record all year; ten songs have been recorded. When this is done I'll go probably write a few more songs," Gwen said last February.

The band's last album was Rock Steady in 2001.
