The 43-year-old country star performed at The Forum in Inglewood, California, as part of his Friends and Heroes Tour in March 2020, where an eyewitness told ET he and Stefani looked more in love than ever. Stefani, who attended the show with her sons -- 13-year-old Kingston, 11-year-old Zuma and 6-year-old Apollo -- also got up on stage to sing "Nobody But You" with her boyfriend of four years, surprising the audience about an hour into Shelton's set. For the show, the blonde beauty donned a denim-and-diamond fringe look, which she paired with thigh-high sparkly boots. Her custom Daniel Diamond jacket even had "Blake" embroidered on the back. 

Rocking emoji leggings, cut-off shorts, white cowboy boots and a checkerboard-adorned sweatshirt, Stefani held hands with her dapperly dressed beau as they walked backstage at the 2020 GRAMMY Awards.

The couple couldn't stop beaming after their GRAMMY duet, where they performed their song, "Nobody But You."

Stefani got up on her tippy toes to get a little closer to her tall BF at the Warner Music Group Pre-GRAMMY Party at the Hollywood Athletic Club in L.A. in January 2020.

They may have been competing against each other, but the lovebirds still looked pretty darn cute posing for pics ahead of the Voice season 17 finale in December 2019.

They may not have walked the red carpet at the 2019 CMA Awards, but the cute couple sure looked happy as they posed for pics inside Nashville's Bridgestone Arena during the ceremony.

Not only did Stefani and Shelton look gorgeous when they walked the red carpet hand in hand at the 2019 People's Choice Awards in November 2019, inside the show, the "Misery" singer couldn't have looked prouder when her beau was named the Country Artist winner during the ceremony. 

The "Misery" singer looked madly in love with her beau as they walked the red carpet together at the Los Angeles premiere of Bennett's War in August 2019.

Stefani looked googly-eyed while staring at her man at the UglyDolls premiere in Los Angeles in April 2019. The No Doubt frontwoman's sons -- Kingston, Apollo and Zuma -- were also there, marking the first red carpet appearance for the five of them.

These two know how to goof off and make us blush! Stefani shared a trio of selfies of the two being just the cutest, captioning the April 2019 pics, "#thankuGOD 4 @blakeshelton." Aw!

Although the two didn't walk the red carpet together at the 2019 Academy of Country Music Awards, they certainly stole the show inside Las Vegas' MGM Grand Garden Arena. Stefani was seen cheering on her man as he took the stage to perform his new single, "God's Country," and they posed for plenty of gorgeous photos.

Messy hair for Shelton, no makeup for Stefani and a cookie cake = the perfect Valentine's Day!

Is there anything more romantic than matching onesies? While celebrating Christmas 2018 with their families, the duo stayed super cozy in reindeer PJs.

After releasing their holiday duet, “You Make It Feel Like Christmas,” in 2017, the singers brought back the love anthem for a joint music video for 2018. Stefani shared a few images from the vid on Instagram, including this sweet scene of the two cuddling up on a couch in a festively decorated living room.

The country music singer took to the stage with his The Voice colleague, Carson Daly, at the 2018 People's Choice Awards, where the two accepted the award for Choice Competition Show, and Shelton couldn't help but show some major love for his significant other. When Daly noted Stefani -- a fellow member of The Voice family -- was in the audience, the Oklahoma native affectionately referred to her as, "My all-time favorite coach on The Voice," adding "I love her!" The awards show romantics didn't stop there, as the couple also shared a sweet kiss for all in attendance to see.

While dressed up as a sailor and Sally from The Nightmare Before Christmas for Stefani's niece, Stella's, pre-Halloween costume party, the couple didn’t hesitate to flaunt some PDA for the camera.

The two looked more in love than ever while vacationing with Stefani's sons in Shelton's home state of Oklahoma in late July 2018, which included a boat trip out on Lake Texoma.

Shelton and Stefani enjoyed a date night at the 53rd Annual Academy of Country Music Awards at the MGM Grand Garden Arena in Las Vegas. While the pair skipped the red carpet, they couldn't have looked cuter sitting side-by-side in the auditorium. During the show, the country crooner took the stage for a performance of his single "I Lived It," as his lady love stared up at him and adorably sang along to the romantic tune, which Shelton appeared to be singing directly down toward her. As his number came to a close, she jumped to her feet to give him a standing ovation.

In March 2018, Shelton had a concert in Houston, Texas, but Stefani was back in Los Angeles, so she posted a sweet throwback selfie of the two. "@blakeshelton have a good show tonight we r missing u in L.A.❤️ gx," she wrote on Instagram.

To celebrate Stefani's youngest son, Apollo's, 4th birthday in February 2018, the proud mom and her beau dressed up as Daphne and Shaggy from Scooby Dooby Doo. Little Apollo was in costume as the iconic pup himself!

The duo made Super Bowl LII a family affair.

The cute couple beat the winter weather by jetting off to Mexico in January 2018. The couple was spotted strolling down the beaches of Playa del Carmen and, per usual, Shelton was making his girlfriend laugh. Stefani, 48, looked sun-kissed and radiant in a white bikini top that she paired with a black sarong and a tan sweater, while the 41-year-old country crooner was seen sporting a blue trucker hat that matched his board shorts and button-down shirt.

Does it get any cuter than this? Shelton and Stefani laughed so hard while backstage during the May 2017 Voice finale that we nearly cried!

While the night away was a family affair, Shelton and Stefani still managed to squeeze in some romantic moments.

He's an amazing person," she said at the November 2016 event.

Later that evening, the birthday boy kept the party going, celebrating with Stefani and his crew at the venue.

The platinum blond beauty pulled out all the stops for the 2016 Billboard Music Awards in Las Vegas, rocking a floor-length sparkly number that perfectly complemented the "Came Here to Forget" singer's dapper ensemble. The two shined as they belted out their duet on the T-Mobile Arena stage.

Following the duo's May 2016 performance on The Voice, the "Misery" singer took to Instagram to share a sweet couples selfie with Adam Levine and Behati Prinsloo.

The No Doubt frontwoman cheered on her beau at the Angry Birds premiere in L.A. in May 2016. Though she didn't walk the carpet, Stefani did share a few selfies of the two hanging out inside the theater before the 3-D animated comedy played on the big screen.

Shelton took his rocker girlfriend to watch the Arizona Cardinals play the Green Bay Packers in Glendale, Arizona, in December 2015.

The new couple held hands while walking between the VIP and main areas of the Warner Music Group CMA after-party in November 2015. In Shelton's other hand was an unmarked white cup, and in Stefani's, a wine glass.

Shelton divorced wife Miranda Lambert in July 2015, and Stefani filed for divorce from husband Gavin Rossdale one month later. Following both splits, rumors swirled that The Voice judges had moved on with each other. Proof seemed to come that October, when they attended two A-list Halloween parties in Los Angeles together. The "Misery" single went all out with her bloody cowgirl costume while Shelton, well, threw on a poncho.

Behati Prinsloo shared an awesome pic of her hubby, Adam Levine, and Shelton decked out in '80s rockstar wigs and denim jackets while Stefani got her glam-yet-edgy princess on. "Comin in hot," the Victoria's Secret model captioned the Instagram from her and Levine's Halloween party.

Well before their romance, the Voice judges posed for an on-set selfie in November 2014, seven months after Stefani initially announced that she was joining the music competition show.
