It’s been a long time coming, but they’re finally back onstage and performing for the world to see. No Doubt, yes, yes — but more importantly, Gwen Stefani’s abs!  

The ska singer and her sick six-pack rocked New York City’s Rockefeller Center last night as part of a pre-game show celebrating the start of the football season.

Gwen and her recently-reunited No Doubt bandmates performed the hit single “Settle Down” from their album Push and Shove, which will be released September 25.

Mariah Carey also took to the stage to perform her new album’s lead track, “Triumphant, Get ‘Em” — a bit of a misnomer, since the track is bottoming out on the charts. Sorry, Mariah.

So, what’s more triumphant here? Gwen’s stomach has our vote.
