Blake Shelton Calls Wife Gwen Stefani 'My Better Half' In Sweet Birthday Post

Blake Shelton gushed over his wife, Gwen Stefani, as he celebrated her birthday on social media over the weekend.

The No Doubt singer turned 52 Sunday, and her husband posted a sweet tribute on Instagram to celebrate the occasion. Shelton shared a black-and-white photo of them dancing together at their wedding.

"Happy birthday to my better half.. my WIFE!!!! I love you @gwenstefani!" he wrote in the caption.

"Love u x," Stefani commented with a red heart emoji.

Many of the couple's fans and followers left birthday greetings for Stefani on the post.

"Aww... Happy birthday, Gwen! We love you so much," one fan commented.

"You both are so adorable!!! Happy Birthday Gwen!!!" a second user wrote.

"Happy birthday, beautiful Gwen! I was able to celebrate my 25 years of marriage and also 10 years cancer-free with you and Blake in Nashville on September 9th. It was a dream that I never thought would happen, but it did!!" another fan wrote.

"Your birthday posts to Gwen are honestly the best Blake," another commented.

Stefani and Shelton tied the knot on July 3 at his Tishomingo ranch in Oklahoma. Weeks after their wedding, the "God Gave Me You" crooner gushed about married life with his wife.

"Married life so far is… it's incredible," he said in an interview ahead of the "CMA Summer Jam," which aired on ABC last month. "I mean, it's everything that it already was, which was awesome. She just can't get away from me now."

This is Shelton's third marriage and Stefani's second. She was married for 13 years to Gavin Rossdale before they divorced in 2016. The former couple shares three sons, Kingston, 15, Zuma, 13, and Apollo, 7.

Meanwhile, the country singer was previously married to Kaynette Williams from 2003 to 2006 and to Miranda Lambert from 2011 to 2015.

An unnamed source told Us Weekly that Shelton feels "different" with Stefani compared to his previous relationships.

"He does feel different in this relationship," an unnamed source said. "Blake is much more secure with Gwen. He can trust her, and there is a mutual level of respect."

Catch Shelton on "The Voice," which airs Mondays and Tuesdays at 8 p.m. EDT on NBC.
