Gwen Stefani Celebrates 40 With Her Cute Boys, Famous Friends and Hot Husband

Gwen Stefani turned the big 4-0 over the weekend and celebrated with a bash at Cecconi's in West Hollywood on Saturday afternoon. In attendance, of course, were her boys Gavin, Kingston and Zuma as well as good friends Kate Beckinsale and Len Wiseman. At the party, Kingston helped blow out the candles while Zuma looked a little tuckered out on mom's shoulder. Before the bash, Gavin snuck in some time to hit the tennis courts and show off his impressive swing — and shirtless six-pack. Gwen looked fantastic as she turned 40 decked out in her signature style and on Sunday it was back to business as usual for the family when Gavin took Kingston to play on a big inflatable slide, Maybe they even got a recommendation from Kate and Len, who tried one out themselves last week.
