The “Make Me Love You” singer not only celebrated her 47th birthday — she also launched her new animated Nickelodeon show, Kuu Kuu Harajuku. Her boyfriend Blake Shelton was there to send her love on both milestones. “Happy Birthday @gwenstefani,” the Voice coach wrote on Twitter. “And congrats on the debut of @KuuKuuHarajuku!!!!” Stefani was thankful for the sweet message. “Thank u @blakeshelton,” she wrote. “What a fun b day boo.” She also took time to send her gratitude to fans. “Had such a fun b day” she wrote on Instagram. “Thank u for all the love and attention. KUUKUUHARAJUKU.” The series focuses on the adventures of a group of Harajuku girls — named, of course, Love, Angel, Music and Baby — who form a band with their leader, G, and fight crime. “I love that this is an animated series for young girls that celebrates creativity, imagination and individuality,” said Stefani — who has three children of her own: sons Kingston, 10, Zuma, 8, and Apollo, 2½. “I can’t wait for everyone to see it!” RELATED VIDEO: Gwen Stefani Snapchats Son Apollo Driving a Boat (with a Little Help from Blake Shelton) Stefani and Shelton have been going hot in heavy for almost a year now.
