Blake Shelton and Gwen Stefani aren't shy about sharing their relationship on social media so there was no way the country singer could let his girlfriend's birthday slip by unannounced.
The country crooner kept it short and sweet, wishing her a happy birthday and congratulating her on her latest project.
"Happy Birthday @gwenstefani and congrats on the debut of @KuuKuuHaraiuku!!!!" Shelton tweeted.
The No Doubt frontwoman is involved in a new animated Nickelodeon show, Kuu Kuu Harajuku.
Monday marked her 47th birthday and the premier of the series, which features the "Harajuku Girls" from her Love. Angel. Music. Baby. album. In the show, they fight crime alongside an animated Stefani.
