As Gwen Stefani’s and Blake Shelton’s relationship has blossomed over the last three years, the couple has proven that they are definitely in it for the long haul. They have remained “inseparable” and are more than just romantic counterparts.

Stefani, 49, told “The Talk” on Tuesday that Shelton, 42, is her “best friend” and she is looking forward to working and spending more time with him on Season 16 of “The Voice.”

“But it’s going to be fun, it’s going to be exciting. I mean, Blake’s my best friend, so I get to hang out with him at work,” she said.

Stefani is replacing Adam Levine, who decided to depart the show. Stefani and Shelton met on “The Voice” and have been dating since fall of 2015.

Despite dating for several years, the couple isn’t ready to get married just yet but definitely enjoys their time together as witnessed by a video that Stefani shared on Instagram of Shelton sneaking in for a kiss.

Last December, Shelton told the “Today” show that his relationship with Stefani is more than “just dating.

He went on to say that their relationship “ is something that I feel like is meant to be. I’ve learned more from Gwen Stefani as a human being, and how to grow as a human being, than I have from anybody ever in my life — anybody.”

Stefani and Shelton have also proven that they have a solid relationship as a source told People that “They’re still madly in love and beyond inseparable. Blake has wanted to take his time with marriage, but he is absolutely committed to Gwen. They both feel they’ve found their true partner in life and plan to be together forever.”

The couple has total appreciation for each other and are “very supportive” of each other in all that they do. The source went on to tell the news outlet that Blake “still thinks he is so lucky that she wants to be with him and thinks she is the most beautiful woman in the world.”
