Blake Shelton's most recent interview took an unexpected turn.

On Monday, "The Tonight Show" aired an at-home episode, during which Jimmy Fallon interviewed the country musician about everything from his music to upcoming episodes of "The Voice." About two minutes into their segment, Shelton's girlfriend, Gwen Stefani, joined him to give him a haircut.

"We actually have a schedule that we already had lined up for today, and I don't think we can put it off any longer," Shelton said before Stefani arrived with a razor in hand.

"We talked a lot about this," Stefani added. "I'm gonna be helping Blake grow out his mullet, so today we had already scheduled that it was haircut day, so I have my clippers, I got my attachments."

"I love seeing Gwen cut your hair," Fallon replied. "This is fantastic. I love this."

During the interview, Blake Shelton asked Gwen Stefani to shave Jimmy Fallon's initials into his hair

"I'm literally putting your initials in my head right now Jimmy, I'm not kidding," Shelton said.

Unfortunately, the letters didn't "show up very well" because of gray strands in Shelton's hair, according to Stefani.

Eventually, Fallon told the couple that Shelton's hair reminds him of Joe Exotic's mullet from "Tiger King."

Shelton has been documenting his 'quarantine mullet' since the end of March

On March 17, Shelton announced through Twitter that he'd be growing out a mullet "as a symbol of hope."

"I have an announcement," he wrote. "With basically EVERYTHING I had scheduled being canceled for the foreseeable further @gwenstefani and I have made a decision together. I am growing my mullet back as a symbol of hope or some s--- like that.. Anyway it's coming back! For real. Stay tuned..."

About one week later, Shelton shared a video of his hairstyle with a new addition: stripes.

"Quarantine mullet update 3/26/2020," Shelton wrote. "@gwenstefani has decided to take it to the next level.. Stripes."

The musicians are just two celebrities out of many who are experimenting with wild hairstyles while quarantined

Like Shelton, Miley Cyrus is also rocking a mullet these days. She first started sporting the style in November 2019, but recently gave herself an at-home trim to enhance her hair. People eventually began comparing the musician's look to that of Joe Exotic, the star of Netflix's new docuseries "Tiger King," and she agrees.

Stars like Hilary Duff, on the other hand, are experimenting with hair dye. The "Younger" actress shared a selfie on Sunday, in which her long, blonde hair was replaced with a short blue bob.

Similarly, celebrities including Ricky Martin, Elle Fanning, and Jennifer Love Hewitt have recently dyed their hair pink.
