Watch No Doubt Perform ‘Settle Down’ Live from Wednesday’s NFL Kickoff [VIDEO]

Before the Cowboys beat the Giants to officially begin the 2012-2013 NFL regular season (and render men around the country utterly useless every Sunday from now until February), No Doubt stood high above the crowd in New York's Rockefeller Center and treated them to a live performance of their new single, "Settle Down".

While they sounded great with the song that sees them lean more on their ska/regge/rock roots, the most impressive thing to me was how great Gwen Stefani looked. The wife of Bush frontman Gavin Rossdale and mother of two looked like she was still in her early-20's with plaid pants and what appeared to be a black sports bra that exposed her washboard board abs. She looks better at 42 than I do at 36.

As they say, "You go girl!"
