Blake Shelton shared a heartfelt birthday tribute to his wife, singer Gwen Stefani, on Tuesday.

The country music singer shared on Instagram a black-and-white photo of the two, all smiles as they gazed into each other’s eyes.

“Happy Birthday to my favorite all time person ever born in any time period in the history of mankind!!!!!” he captioned the post. “I love you @gwenstefani!!!!!!!!!!”

Stefani thanked her fans and loved ones for all of the celebratory birthday messages she had received in her own Instagram post on Tuesday. The “Don’t Speak” singer received several birthday messages from other celebrities, including a note from her fellow coach on “The Voice,” John Legend.

“Happy birthday Gwen!” he wrote in the comments section of Shelton’s post.

“The Voice” host Carson Daly also commented on Shelton’s post, but he appeared a little less enthusiastic about the country singer’s display of affection.

“Get a room..” he quipped, adding a nauseated-face emoji.

Stefani and Shelton met while taping “The Voice” in 2014. They became engaged in 2020 and married the following year.

The “Hollaback Girl” singer has three children with ex-husband Gavin Rossdale: sons Kingston, Zuma and Apollo.

She told People magazine in a cover story last week that the start of her relationship with Shelton was unexpected.

“I didn’t see any of this coming with Blake. This was just a big old ‘What?’” she said. “It was an amazing gift to experience love like that for the first time.”

She added, “He’s changed my life … when I [started dating] Blake, that’s when I felt home, like, ‘Oh, this is where I’m supposed to be, with this guy.’”
