Gwen Stefani and Blake Shelton's Relationship: An Obsessive Timeline

Gwen announces she is joining the The Voice as a judge. This will be the beginning of their working relationship and friendship.

Blake makes his first appearance on Gwen's Instagram page. She wasn't shy about her affection for him, even in the beginning.

Things heat up on the set of The Voice as Gwen and Blake grow closer to each other. (I mean, she's literally sitting on his lap...)

Rumors are circulating Gwen and Blake are an item but neither of them have made an official statement. During a guest appearance on On Air with Ryan Seacrest, Seacrest plays no games and asks Gwen whether she and Blake are dating. She refuses to answer but does disclose that she "think[s] he's hot." We already knew that Gwen.

Blake gifts Gwen a horse, Halo, which is presumably a Christmas gift. Clearly the pair is getting closer—Gwen's California style is already getting a little more country.

Gwen discusses how her relationship with Blake started on The Ellen DeGeneres Show. Initially, Gwen says she “thought it would be a good idea not to talk about Blake,” but Ellen went for it. She asked how Shelton “popped the question” of Gwen being a mentor on The Voice. Gwen is obviously very into Shelton, but protective of their new relationship.

Gwen and Blake spend his birthday together.

You know when you see people so in love their happiness rubs off on you? That's how you'll feel after watching this video of Gwen. She could not stop talking about how great Blake is during her appearance on Jimmy Fallon's show. Stefani talks about taking him to Disneyland and spending time with her family—and is clearly smitten.

Gwen and Blake turn the cuteness level way up on The Gwen Stefani Christmas Special. They performed their duet off Gwen's Christmas album, You Make It Feel Like Christmas.

Gwen goes on Ellen and is put on the spot regarding marriage proposal rumors. Gwen starts by saying Blake got “sexier. And it just keeps getting better” after being named People’s 'Sexiest Man on Earth.'

Gwen did not confirm or deny a proposal, but did say, “We all love him” and that she thinks about marriage “all the time.”

Gwen starts her Las Vegas residency at Planet Hollywood with Shelton there to support her. The pair engages in some very public PDA on Twitter, Gwen adding #BestBoyfriendEver to her tweet.

On The Ellen DeGeneres Show, the talk show host gifts the country singer a clock with his and Gwen's face on for a very special reason. Apparently, the last time she gifted the time-telling gift, it was to Jennifer Lopez, who got engaged to Alex Rodriguez shortly after.

"So you're saying there's a chance she's going to ask me to marry her?" Shelton joked when he got the gift. "You see how I flipped it around and put it on her?"

On TODAY, host Hoda Kotb asks Gwen if she thinks Blake would be a good father. The singer responded with instead, "He is a good dad, actually." Aww!

She continued,"He’s been helping me out a lot. I literally get to the point where I’m like, 'You gotta get home, I need help.'"

When Blake and Gwen dropped their third song together, "Nobody But You," the lyrics said A LOT. In an interview on Entertainment Tonight, the reporter brought up how the lyrics, "I don't wanna look back in 30 years and wonder who you're married to" weren't helping the rumors swirling around that they've secretly got married.

Shelton responded, "I love the rumors. Those rumors are great. Anybody that thinks that I'm married to Gwen already, I love it. My God. Who wouldn't want to be married to Gwen Stefani?"

Gwen and her three kiddos made a surprise appearance at Blake Shelton‘s Los Angeles concert, and even joined in on singing their duet, "Nobody But You." Obviously, with a moment as cute as this, she had to document it.

“He’s so fun and has shown Gwen’s kids another side of life filled with adventure,” a source close to Gwen told PEOPLE of Blake's relationship with her kids. “The boys have really grown immensely by spending time with Blake.”

Despite the setback of quarantine, Blake and Gwen showed us they could still have fun doing the smallest of tasks: like a haircut at home.

“We learned how to make bread real good, sourdough bread,” Shelton said on The Tonight Show with Jimmy Fallon of what they had been doing to keep busy at-home. “Literally it’s like Little House on the Prairie here. She makes bread, I’ve been building a fence and gardening. We’re pretty self-sufficient out here.”

If you thought the duets between these too would stop because of a pandemic, think again! The couple dropped their fourth song together, "Happy Anywhere," with an equalling cute music video.

"An Okie boy and a California girl look on paper like an unlikely match, but what matters is she's a great human being," said Blake to PEOPLE on Gwen. "She is the most understanding, kind-hearted person I've ever met and I learn something from her every day. "

They're engaged! In an Instagram post showing off her new ring, Gwen wrote: "@blakeshelton yes please! 💍🙏🏻 gx"

Stefani gave fans an update about wedding planning, revealing that the pandemic has made locking down a date difficult. “We can’t really plan the wedding because we don’t know what’s happening. I think we’re just sort of putting a target date out there and seeing if we can work backwards,” the singer told ET Canada. She also revealed she's still shocked about being engaged. “I never expected that this would be where I’m at,” Stefani explained. “It’s hard for me to even say I’m getting married. I’m like, so in the middle of my life.” As for wedding details, she shared the nuptials would be a "spiritual experience," and Miley Cyrus may or may not be singing at it.

The couple proved they have an A+ sense of humor when they poked fun at their relationship in a Super Bowl ad. In the spot for T-Mobile, the Voice co-stars showed how they "got set up" on a date by Adam Levine—and how they didn't exactly hit it off at first because of their very different lifestyles. Spurs and punk rock aren't the most expected pairing, but hey, things worked out for them.
