Gwen Stefani Rocks Out With Her Rock Hard Abs On Display

After all these years, she still knows how to rock - and look sexy doing it!

Gwen Stefani hit the stage last night with her No Doubt bandmates to perform their hit single "Settle Down" at the 2012 NFL Kick-Off Concert at Rockefeller Center in NYC, and the punk princess went back to her ska roots in plaid pants, combat boots, and a midriff-baring tee that showed off the results of her daily workouts! We can't believe Mrs. Gavin Rossdale has given birth to two kids... look at those abs!

The blonde beauty and her band are gearing up to release their new album, Push and Shove, on September 25, and not only that but they also just announced they will be putting on a series of shows at the Gibson Amphitheatre in L.A throughout November.

How does the 42-year-old juggle all her work and family responsibilities?

"It's not possible. There are always days that somebody suffers. The only thing I really worry about is, again - I keep bringing it up because it's my biggest stress - how do I do this and that? How do I do both? So that's like the constant battle that I have every day. I do worry about that all the time," the singer recently confessed to Elle magazine.

Don't worry Gwenny, it looks like you're doing an amazing job multi-tasking!
