Gwen Stefani seems to never get tired nor age! Yep, we're jealous.
The 43-year-old No Doubt songstress showed off her rockin' abs while performing with her band for Jimmy Kimmel Live.
The blonde rocker and the boys were there to help usher in Jimmy's new time slot. Wow ... Jennifer Aniston AND Gwen for the first show! Pretty impressive.
Even while arriving to Kimmel's studio, Gwen was picture perfect. Loves those shades!
