“It’s a special day for a special lady in my life. Happy birthday @gwenstefani, I’d write a song for you every single day if I could...” he captioned a photo of himself holding a guitar in what looks like a cornfield while Stefani leans on his arm.

The “Voice” coaches, who confirmed their romance in 2015, continue to go strong and have even teamed up on a pair of duets, “Nobody But You” and “Happy Anywhere,” which they unveiled during quarantine.

Stefani and her children that she shares with ex-husband Gavin Rossdale, Kingston, 14, Zuma, 12, and Apollo, 6, spent time with Shelton while quarantining.

"It's been pretty magical for Blake and I and the kids because we don't ever have that much solid time together," she said in a clip for the upcoming season of “The Voice.” "We did do a lot of fun stuff. We did a lot of cooking."

Some other fun stuff? Stefani gave her man a mullet hairstyle and also cut and dyed his hair.

"We ordered some Just For Men and I tried that for a while, and I wasn't doing it right and it wasn't, it had too much color — it was like blue or purple or something," Shelton said last month on “The Ellen DeGeneres Show.”

"(Stefani) said, 'Let's just do it right.' And at that time I didn't care because nobody's going to see me, we were quarantined, so that was the time to mess around."
