It has been nine years since No Doubt released any new material and fans could be forgiven having doubts that No Doubt may have run their course.

However the band have released teasers from their new single Settle Down.

It is only 26 seconds long, but shows Gwen Stefani back with the band and a taste of what is to come.

The band shot to fame with singles such as Don't Speak' and Hey Baby.

Although they have been touring and performing in recent years, their new album Push and Shove will be their first studio album since 2002.

The single will be released in September.
