Gwen Stefani and her singer boyfriend Blake Shelton dressed up as characters from Scooby-Doo on Sunday (25Feb18) to help her youngest son celebrate his fourth birthday.
The mother-of-three threw a Scooby-Doo-themed party for little Apollo, the youngest kid from her marriage to ex-husband Gavin Rossdale, and she got into the costume spirit by attending the bash as Daphne Blake, donning a red wig and a hair band to go with her purple dress and green scarf.
Boyfriend Blake, who is currently in the middle of his Country Music Freaks Tour, also took part by disguising himself as Shaggy Rogers from the beloved cartoon, with Gwen sharing a few snaps of the couple on her Instagram Story profile.
The party also featured a bouncy house and a puppet show to keep Apollo and his friends entertained.
The celebrations took place just hours after Gwen surprised concert-goers at Blake’s show in St. Louis, Missouri on Saturday night (24Feb18) by joining him onstage for an unexpected appearance.
She has since posted multiple close-up snaps of the pair’s romantic embrace at the end of the set on Instagram.
Gwen and Blake, who began dating in 2015, previously shared the stage on numerous occasions to perform their 2016 duet Go Ahead and Break My Heart, while they reunited in the studio last year (17) to record You Make It Feel Like Christmas, the title track from the No Doubt frontwoman’s holiday album.
