Their comment sections were flooded with sweet congratulatory messages, with Dua Lipa cheekily writing under Stefani's post, "I guess our little interview aged well," in reference to when Lipa took over for Jimmy Kimmel back in August, and accidentally asked the "Hollaback Girl" singer how quarantine was with her "husband Blake Shelton."
"Well, he's not my husband but that sounded cool when you said it," Stefani replied at the time, clearly dreaming of this romantic day.
"CONGRATS GWENNNNNNNNNNNN," Julia Michaels commented, while Ellen DeGeneres wrote, "This shot is bananas. Congratulations!"
"WOWWWWWWWW CONGRAAAAAATS," Ryan Tedder mirrored, while Jimmy Fallon opted for a short but sweet, "Congrats!!" with a red heart emoji.
"Woooo way to lock it down Blake!" Lauren Duski commented on Shelton's post. "So happy for y'all!!!!"
The couple also got some celebratory tweets from John Legend, Dan + Shay and more. See them below.
