Blake Shelton and Gwen Stefani are marking a special milestone — four years of marriage — and their sweet messages prove that their love is stronger than ever.

On Instagram, Gwen, 55, shared a touching video filled with beautiful moments from their journey together. The montage showed the couple kissing, laughing, and sharing quiet, loving glances — all set to their duet “Purple Irises.”

“7-3-21. Every day I thank God for you @blakeshelton. Happy anniversary. I love you so much,” Gwen captioned the post, showing just how thankful she is for Blake and their life together.

Blake, 49, responded with his own loving tribute, posting a photo of their wedding kiss. “My pretty girl… I’m the luckiest man to be married to you and to know you. I love you @gwenstefani!!!!!! Happy anniversary!!!!” he wrote, making fans swoon.

The pair tied the knot on July 3, 2021, at Blake’s ranch in Oklahoma in a cozy ceremony led by their friend The Voice host Carson Daly. Carson later shared his joy about the day, writing, “So honored to get to marry two of my favorite people on earth. May God bless you guys in this new chapter of your lives. We love you!”

From TV Co-Stars to Soulmates

Blake and Gwen’s love story began back in 2014 on The Voice, where they met as coaches. At the time, both were going through painful divorces — Gwen from Gavin Rossdale, and Blake from Miranda Lambert.

By 2015, the two found comfort and support in each other, forming a deep connection during one of the toughest chapters of their lives. Gwen later said in an interview that it felt like a miracle: “It was unbelievable that God would put us in a position to have each other at that moment.”

Though neither expected to fall in love, their bond grew naturally. They went public as a couple in late 2015 and made their red carpet debut in early 2016. Blake popped the question in 2020, and Gwen’s answer was simple: “Yes please!”

Blended Family and Shared Dreams

A big part of their happiness comes from how they’ve built a loving blended family. Gwen’s sons — Kingston, 19, Zuma, 16, and Apollo, 11 — have grown close to Blake, who proudly embraces his role as a stepdad.

Blake once said, “If I could have a repeat of these past 10 years, that would be perfect.” And it’s clear he means it.

The couple continues to make music together, with hits like “Nobody But You” and their latest duet “Purple Irises.” Gwen even returned to The Voice in 2022, joining Blake on the show where it all began.

From co-stars to partners in life and music, Blake and Gwen’s story proves that sometimes the best love comes when you least expect it.
