Ellen DeGeneres also wished the Sweet Escape hitmaker with a playful animated GIF of herself popping out of a cake. "Happy birthday to my friend, @GwenStefani! This GIF is bananas," the daytime TV host wrote on Twitter.

When Stefani appeared on The Ellen DeGeneres Show in September, the host had taken it upon herself to find out whether the songstress was planning to marry Shelton. However, Stefani just laughed it off.

"I just need to know so I can clear that schedule," DeGeneres had asked jokingly. "Oh, you're crazy," Stefani told her. "Just let me know," said DeGeneres, to which Stefani replied, "OK. I'll let you know."

Shelton and Stefani have been dating since meeting on the sets of The Voice.
