Gwen Stefani Needs A Break

Yesterday we spotted Gwen Stefani enjoying some time with her family in Malibu, and there was no doubt that the singer looked amazing, but she also looked quite exhausted by the end of the day! Her sons Kingston and Zuma sure are cuties, but we bet they're a handful!

Or is a possible pregnancy what's wearing her out? The baggy clothes and strategically placed hands are certainly making us wonder!
