Gwen Stefani shared a rare photo and video of her eldest son Kingston to celebrate his fourteenth birthday.

The mother of three first shared a sweet photo of Kingston James McGregor Rossdale on Tuesday (May 26). "Happy 14th bday to my first born son - thank u [sic] God for marking me HIS MAMMA," the "Nobody But You" singer captioned the beach snapshot.

Stefani followed up her initial photo with a video of Kingston and Stefani’s boyfriend, Blake Shelton. In the clip, Shelton is seen donning a Hawaiian shirt while he smothers and kisses Kingston on the forehead multiple times in a joking manner, before Kingston playfully wipes his face.

Stefani has three children with her ex-husband, Gavin Rossdale. The pair share 14-year-old Kingston, 11-year-old Zuma Nesta Rock Rossdale and 5-year-old Apollo Bowie Flynn Rossdale.

Gavin also paid tribute to his firstborn son with an Instagram post. "What a journey with this young man," the Bush frontman wrote.  "King, you blow me away. Such a kind funny smart handsome naughty spirited articulate dynamic sapien."

His father also poked fun at the fact that his son requested and advertised a large party, which the family will not be having due to the pandemic. He did promise that it will come in the future once the world becomes safer, though.
