No Doubt About Their Love: Gwen Stefani and Blake Shelton's Relationship Timeline, From 'The Voice' to Wedded Bliss

Gwen Stefani officially joined NBC's The Voice as a coach. She secured a spot on the judging panel alongside Pharrell Williams, Adam Levine and Blake Shelton.

She was still married to Gavin Rossdale, while Shelton was still with his then-wife, Miranda Lambert.

A few months after they first met, Stefani and Shelton filed their respective divorces from their partners.

Shelton broke up with his fellow country singer in July, while the What You Waiting For? hitmaker called it quits with Rossdale in August.

In her interview with Howard Stern, Stefani admitted "going white" after her fellow The Voice judge revealed his split.

"It was during that time, he came up to my chair," she recalled. "I never saw him look so upset. So then I was like, 'I gotta talk to you.'"

From there, a spark kindled between them.

After becoming singles, Stefani and Shelton gave their relationship a try and started dating.

A representative for the now 47-year-old God's Country singer confirmed their romance to People after dating rumors emerged following their Halloween weekend date.

"Blake and Gwen have begun dating," an unnamed insider said. "They've been supporting each other through a difficult time and they're really happy together. Everyone is thrilled because they're both incredibly nice people."

Stefani and Shelton marked public outings in the months following the confirmation of their relationship. But they made everyone's hearts flutter even more when they performed together for the first time at the Billboard Music Awards in 2016.

The couple sang Go Ahead and Break My Heart, which they wrote together.

A year into their relationship, the couple sparked engagement rumors that even Ellen DeGeneres quizzed Stefani regarding their wedding date.

The 53-year-old Hollaback Girl singer revealed in an Instagram post that Shelton officially popped the question after five years of dating.

Stefani and Shelton tied the knot in an intimate ceremony at the male crooner's Oklahoma ranch, where he built a small chapel specially made and built for the occasion, Page Six reported.

"They don't want a huge wedding," a source said months before the ceremony. "They want their family and close friends to attend and that's it."
