The Curious Case of Gwen Stefani's Abs

There are a few concerts that I need to watch in my lifetime:

1. Justin Timberlake: Need to get my "Sexyback."
2. Janet Jackson: Homegirl can dance.
3. Black Eyed Peas: Cross that off the list. Thanks CeCe Jie. :)
4. No Doubt. <<<<

This is the Cricket Wireless Ampitheatre. A few Coyotes and I headed down south to Chula Vista, San Diego after scoring some amazing $20.00 to see Gwen Stefani & Co. yell, "Hey Baby," to us.
Yea, yea. No Doubt rocked. They played all the awesome oldies. They had an awesome stage. They looked great. But in all honesty, Gwen's abs stole the show.
Want a closer look?
We were mesmerized. We were entranced. We were captivated. How can you be 39-year old, have two kids and look like that?

My personal theory is that she's an alien robot.

Anyway, after the show, we decided to try our own No Doubt moves.
And jam to our own No Doubt beat.
Next step: cloning Stefani's abs.
