It's been over a decade since No Doubt took the stage at the Teen Choice Awards, and on Sunday night (July 22), it looked like no time had passed since they last stormed the show in 2001 during their Rock Steady days.

Gwen Stefani had her ska-loving swagger turned up to 10 as she performed the band's [article id="1689698"]new single "Settle Down"[/article] live for the first time alongside her longtime musical comrades. The entire band wore black-and-white everything, so the focus of the super sparse performance was all about the foursome, with no bells and whistles to distract the room from the iconic rockers.

In fact, Stefani seemed perfectly comfortable sharing this sentiment with the room: "I'm fine (And nothing's gonna knock this girl down)/ I'm hella positive for real, I'm all good/ I'm fine (And nothing's gonna knock this girl down)/ It's gotten complicated, that's for sure."

While many of the music lovers in the audience and at home watching were babies -- or, in some cases, not even born -- when the band skyrocketed to fame in the '90s, they couldn't settle down their excitement at welcoming No Doubt back to the scene.

The performance is a big tease to the release of the band's September album, Push and Shove. Earlier this week, the SoCal rockers released their Sophie Muller-directed [article id="1689845"]video for the ska-infused track[/article], which followed the foursome as truck drivers on the road to a big parking-lot hoedown. The single was produced by Diplo, who worked with the group on their forthcoming project, their first [article id="1689698"]studio album release[/article] in more than 10 years.
