The former No Doubt frontwoman had more than one reason to party it up—the mom of two's new Nickelodeon series Kuu Kuu Harajuku premiered on the same day—and her crooner boyfriend was quick to publicly share how proud he was of her.
"Happy Birthday @gwenstefani and congrats on the debut of @KuuKuuHarajuku!!!!," the Voice coach wrote on Twitter to his love. Seriously, could these two get any cuter?
The "Make Me Like You" hitmaker took to Instagram and Snapchat herself to share photos from her birthday celebration. "It's my b-day," she wrote in pink lettering across a photo of herself rocking a sparkling tiara. She also shared a shot of herself in her birthday crown while showing off her birthday goodies.

The platinum-haired beauty also took to Instagram to share an image of herself watching her new show. "Had such s fun b day! Thanku for all the love and attention KUUKUUHARAJUKU Gx," she captioned the post.
Shelton doesn't appear in Stefani's celebratory Snapchats or Instagrams so the question remains: Just what did he get for the birthday girl?
