Gwen Stefani is the coolest chick alive.

Whether she's rocking out as part of a faux '80s band on Gossip Girl, debuting the trendiest fashions, looking far too good to be 39 years old or just hangin' with her husband and young sons, the No Doubt singer is always a breath of fresh air.

All together now: Awww ...

BABY CRAZY: With two sons in the past three years, will Gwen and Gavin Rossdale aim for a third? It's hard to argue against expanding this level of cuteness.
