She’s his No. 1 fan! Gwen Stefani couldn’t help gushing over boyfriend Blake Shelton’s soon-to-be-released new album via Twitter on Saturday, March 5.

After American Idol alum Kelly Clarkson praised Shelton’s album, Stefani hopped on social media to add her opinion as well.

“It’s SO good @blakeshelton :) The whole new album is amazing!” Clarkson, 33, wrote. “Can’t wait for everyone to hear it! Killer job!”

“@kelly_clarkson @blakeshelton sooooooo good #newmusic #gottohearitfirst #lucky,” Stefani, 46, wrote back.

Later that day, the “Make Me Like You” singer was spotted by fans in Nashville showing her support for her main man.

“@blakeshelton … Is that @gwenstefani we spy watching you perform tonight in Nashville!! #blakeshelton #BSers #BSVIP #nashville #blakesheltonnashville #goodtimes,” one user captioned a photo of a blonde-haired Stefani in a black jacket and bright-pink miniskirt.

“Maybe…” Shelton, 39, replied via Twitter with a winking emoji.

At the show, fans caught the L.A.M.B. designer singing along to Shelton's songs, even pointing to her boyfriend while mouthing the line, "God gave me you for the ups and downs.” At the end of the song, the country singer hopped off the stage to give Stefani a big kiss.

Stefani Snapchatted throughout the show, adorably adding commentary to the video clips.

“Wow,” she wrote in red, encircling Shelton’s face on a monitor with a heart.

At another point, she wrote, “Good song” with a kiss emoji face.

This isn’t the first time the “Used to Love You” singer has fangirled over Shelton in concert, however. In February, she watched his Detroit show via FaceTime.

“It’s poppin’ off!” their fellow Voice coach Pharrell Williams said of the couple during an interview with the Today show last week. “It’s so beautiful because being there, I watched both of them go through a lot, you know. You hate to see your friends go through something so heavy, and it’s kind of like a miracle, man — just watching that.”
