Brian Kelley has officially been unveiled as the singer behind the Mad Scientist Monster costume on the reality singing competition, The Masked Singer.

Brian Kelley Revealed As Mad Scientist Monster On The Masked Singer

While it was clear since the Mad Scientist Monster made his debut on the March 26 episode of Season 13 that the person singing was a country star, the four panelists weren’t so quick to guess Brian Kelley. Instead, Robin Thicke, Jenny McCarthy-Wahlberg, Ken Jeong, and Rita Ora threw out names such as Luke Bryan, Luke Combs, Blake Shelton.

Kelley may be a country star at his core, but his character made sure to showcase songs across all genres, including “Love Yourself” by Justin Bieber, “Stay” by Sugarland, “There’s Nothing Holdin’ Me Back” by Shawn Mendes, “Unwell” by Brett Young, “A Bar Song (Tipsy)” by Shaboozey and more.

As the season went on, Kelley still had the panelists stumped as they added to the list of potential country stars with names like Gary LeVox of Rascal Flatts, Kane Brown, Jelly Roll, Alan Jackson, Tim McGraw, and Keith Urban. However, between the performances and clues that involved messages about how he met his wife, milestones in his career as part of the duo Florida Georgia Line as well as his solo venture, nods to his days as a college baseballs player and more, many fans were able to put the pieces together.

Unmasked On May 7 And Opened Up About His Experience

On the latest episode that aired on Wednesday evening (May 7), the rumors were finally confirmed – Brian Kelley was behind the mask.

“It was a blast to watch it all go down. You kind of think maybe you know how it may play out and maybe not many people are going to know, and I feel like for the first couple weeks some people were guessing, and then after every episode the last couple of weeks, I’m like, alright, I think they’re onto me for sure. People are doing their research and I think the super fans that know me were instantly, that’s BK,” he explained to Country Now during Media Row at 2025 ACM Awards.

Kelley Is Grateful For The Opportunity

Overall, the “Beach Cowboy” singer stated that his time on the show was a “great experience” and that he is “forever grateful for that opportunity.” He noted how it gave him the chance to relieve any pressures he may have been feeling and simply enjoy the ride.

“It was such a fun time. It was such a different way to go about getting my voice out there and getting my story out there some. And I’m competitive. I grew up playing college baseball, love a challenge. I love competing. And so that was a different way to do that, and it was freeing,” he admitted. “It was oddly freeing and recentering and recalibrated myself during that experience. Just taking off any, I have to be a certain way, or I’m only this kind of singer and just truly being myself and letting it fly was awesome. It was a great experience. I’d do it again in a heartbeat.”

Since his time on the show has come to an end, it’s time for Kelley to say goodbye to the costume that has kept his identity a secret throughout the entire journey. He joked that despite the green and purple ensemble being “pretty hot,” it was nothing he couldn’t handle as a Florida native.

“Growing up in Florida, it’s nothing I hadn’t faced, so I had a hand up in that area, but they were real collaborative with songs and everything, and they really knocked out the creative the first call. They’re like, ‘Hey, we’re thinking mad scientist monster.’ I’m like, love it. And then they showed me kind of a picture of what that is. I’m like, I’m in. Love it. That’s totally me. Yes, it’s weird. It’s awesome.”

New Music On The Way From Brian Kelley

Now Brian Kelley, formerly of award-winning duo Florida Georgia Line, is ready to get back to the music. His latest solo release, “Palm Tree Country” serves as the perfect coastal introduction to his just announced Sunshine State Of Mind Tour. The trek will feature a full band and a full projection, which Kelley noted is his “favorite” way to tour.

“We love doing our Surf Post Sessions down where we live, a more stripped-back vibe, but when we’re touring, we got full production, full band. And my team, we’ve been building for a couple good years now, and I feel like we’ve got our travel, our show, our vibe, everything’s really dialed in, and we’ve been waiting for this moment to get out there and do another headline tour. It’s been a couple of years since we’ve done a proper headline tour, and we’ve been kind of in build mode. We’ve done festivals, we’ve done a bunch of radio shows, we’ve done different things and excited to circle back and show fans like how we’ve grown in those couple years with our show.”

In these few years off the road, he has grown his catalog of songs and is ready to showcase his current chapter as an independent artist while leaning into fans’ desire to hear more and more music.

“Just enjoying it. Life is good. I got no complaints and it’s been a fun year. It’s been my favorite year of life so far this year, honestly. It’s been great. It’s been a lot of work and also a lot of play. It’s been a good mix,” he shared.

Named after his 2021 project, the upcoming trek will kick off July 24 in Savannah, GA and continue through South Carolina, Florida, Tennessee, Georgia and more before wrapping up in Raleigh, NC on September 7.
