Gwen Stefani and Blake Shelton's Relationship Timeline as They Release Duet

Gwen Stefani and Blake Shelton are melting the hearts of fans and proving their relationships is something to emulate as the pair released a romantic duet this week.

The couple of five years made a huge declaration of love by teaming up for a new track, "Happy Anywhere," which dropped on Thursday night in what is shaping up to be a big week for music lovers.

"Even though Gwen and I just had a single out we decided that, under the circumstances, this year... man, there's never been a better time for 'Happy Anywhere,'" Shelton, 44, said in a statement. "We've all been in quarantine and lockdown, and hopefully we've been doing that with somebody that we really love and enjoy being around. That's what happened with Gwen and me this summer—and this entire year."

Later, in a livestream to promote the song, the country star opened up about collaborating with his wife, who is not known for her performing the genre, saying: "It's hilarious that listening to the radio the last couple of years that Gwen Stefani is going to be singing the 'countriest' song to come out of Nashville... It's ironic. It's funny."

"We are real people, with real lives, with real families, friends and colleagues. Therefore, we kindly ask for privacy and compassion concerning this very personal matter."

Then as fate would have it, one month later, Stefani split from her husband of 13 years, Gavin Rossdale.

The couple, who married in 2002, and share three kids, filed for divorce in 2015 citing irreconcilable differences.

In a statement to People at the time, the exes said: "While the two of us have come to the mutual decision that we will no longer be partners in marriage, we remain partners in parenthood and are committed to jointly raising our three sons in a happy and healthy environment."

2016

Ever the cowboy, Shelton gifts his new girlfriend a horse for her birthday and Stefani gushes about it on Instagram.

Shelton told ET: "I got her a horse and I got myself a horse at the same time. Gwen, she loves riding and she loves horses. It's actually so funny that people are so shocked by that, but if you can name me one girl on the planet that doesn't love horses or just thinks that they are beautiful."

In February, the couple attended their first red carpet together at the Vanity Fair 2016 Oscars afterparty.

They perform another duet together in May at the BBMAs of "Go Ahead and Break My Heart" in May and in June, Shelton told Billboard that Stefani "saved [his] life."

He elaborated: "It's so funny. They found each other at really interesting times in their lives. It's really beautiful. Because it's in the public eye, a lot of people want to have their own bullshit opinions about it, but I'm, like, there. I see it every day. I have a pretty unique perspective on it, and it's real, man."

Shelton is catapulted to higher levels of fame in February after he's named Sexiest Man Alive.

Stefani jokes about her man's new accolade to Ellen DeGeneres, saying: "He doesn't even like to do a photoshoot. You can never convince him to do it. So he just called me like, 'They want me to do this.' And I was like, 'You should totally do it! You're so sexy!'"

They then perform another loved duet of "You Make It Feel Like Christmas."

Later that day, Stefani responded: "OMG just seeing this now!! I love you! #Bestboyfriendever #favoriteperson."

In July, Stefani admits she is "super in love" when telling In Style about her style becoming more feminine. She said: "It's probably because I'm super in love and have a really manly man [Blake Shelton]. I enjoy letting that part of me come out.

The couple celebrated four years together in June this year.

"It's actually shocking that it has already been that long," Shelton told People magazine. "It's kind of a blur. It still feels like it's pretty new to me. I guess it is, relatively. Four years isn't forever, but man, it seems like it just happened in no time."

2020

In June 2020, US Weekly reported that Gwen wants to marry Blake when the coronavirus pandemic is over.

Shelton also told ET that he "loves" the wedding rumors.
