The fantastic No Doubt have finally unveiled their brand new single, 'Settle Down'.

The highly-anticipated offering premiered earlier today (July 16) and has been warmly welcomed by fans around the globe. 'Settle Down' is available to purchase now via iTunes.

The group reconnected with long-time collaborator Sophie Muller for the upcoming video and she recently revealed the concept behind the visuals to the Rolling Stone: "The idea is they are all driving to meet after having had their separate lives over the last 10 years."

"Lyrically it’s not really a party song. It’s got a real emotional desire to get through something. You have a combination of this party feel with her struggle to be able to express herself."

Member Tom Dumont tweeted about the song's impending reveal this morning and wrote: "Gotta sign off w 30 minutes to go. Sleepy boys here...G'nite folks, we awake to a new song and a new era!"
