Gwen Stefani park coldwater playground blonde singer

Gwen Stefani knows how to make a fashion statement ... even if she's just kicking back barefoot at Coldwater Park in Beverly Hills with her boys. We can't get enough of her sexy style!

The No Doubt singer, wearing a striped off-the-shoulder shirt and plaid paperboy hat, totes around adorable son, Zuma, who is rocking a mini version of mom's cap. What a cutie!

Check out Kingston sporting blue toe nails while carrying around his Mack truck. This little boy is definitely following in mom's rock star footsteps.

We love how Gwen is so hands-on with her kids. Looks like daddy Gavin got to spend the day alone. Lucky guy!
