Gwen Stefani Looks Damn Good At 43

We've come to the conclusion that Gwen Stefani must have discovered the fountain of youth, because homegirl just doesn't age.

On Monday, the platinum blond singer was spotted grabbing some healthy "smoothies" with husband Gavin Rossdale in London. We say "smoothies," because we're convinced the cups of green goop must really be Stefani's secret to looking so damn good at 43.

While there is no denying the No Doubt singer works out, stays out of the sun like its her job, and generally takes great care of herself, we feel that she must have a secret weapon up her sleeve.
