Zoinks! Gwen Stefani and Blake Shelton Dress Up as 'Scooby-Doo' Stars

Gwen Stefani and Blake Shelton were serving up Scooby Snacks over the weekend when they dressed up like the famous mystery solvers.

The "Voice" stars transformed into Daphne Blake and Shaggy Rogers for the fourth birthday party of Stefani's son, Apollo.

She looked the part in a retro purple top complete with Daphne's signature green scarf and red hair. Shelton's character was a little easier to portray, with scruffy hair and a green shirt.

For entertainment, they of course had a Scooby-Doo character roaming around, along with a marionette theater for the kids. Luckily, no evil villain was hiding in the Scooby suit to sabotage the party.
