Gwen Stefani blonde park coldwater playground singer Gwen Stefani blonde park coldwater playground singer Yesterday, Gwen Stefani wore a sheer black top that showed off an electric blue bra for a day at the park with her two sons, Kingston and Zuma.

The kids who got our vote for cutest costumes looked just as adorable unmasked as they did on Halloween, but their mom, who went as Jessie from Toy Story, somehow managed to look more conservative on the traditionally wild night than she did the day after!

Course, Stefani's no stranger to wacky outfits worn while watching her kids, but in the words of Valerie Cherish, "I don't wanna SEE that!" Especially not with her boys around!
