Blake Shelton hilariously pranked Kelly Clarkson on Monday's episode of The Voice, secretly playing the song 'Don't Speak' every time she spoke.
The 43-year-old judge had his buzzer configured to blast the 1995 song by his girlfriend Gwen Stefani's band No Doubt and used it throughout the auditions.
But his fellow judge, Kelly, 37, got her licks in, too, blocking Blake from taking a singer he wanted, and confusing him into blocking himself another time.
Good one: Blake Shelton pranked fellow judge Kelly Clarkson on Monday's episode of The Voice by secretly playing the song 'Don't Speak' every time she spoke
Blake had initially stirred things up by taunting Kelly that she would never use her block on him, saying she didn't recognize talent as easily as he did.
Kelly finally did block him—on singer Marybeth Byrd, 18—so he resorted to his little trick, repeatedly playing the song over the loudspeakers, and making his friend crazy.
'The Don't Speak music? That was me,' Blake crowed to the cameras as Kelly blamed a crew member. 'I can't wait to do it again, because Kelly blocked me. She can kiss my butt.'
The God's Country singer then accidentally ruined his own prank, hitting the buzzer for emphasis as he made his pitch to Las Vegas singer Kiara Brown, 21.

'Ahhhhh!!' Kelly screamed, running over to him in disbelief. 'You did do it to me!'
Judge John Legend, 40, pushed Blake's buzzer and the song played again.
'You sit on a throne of lies!' Kelly exclaimed, punching Blake in the arm.

Gwen, 49, echoed her sentiments, saying, 'I can't believe you just lied to me.'
'No, no! I love you,' Blake protested.
As he weakened, Kiara ended up choosing his girlfriend, Gwen, to be her coach.

'Kiara was so good and I loved her performance, and then I hit my button and it just completely derailed everything,' Blake said. 'It sucked.'
'If there's one lesson I learned today it's that I've got to be better at lying.'
'That was maybe my favorite part of anything I've seen on The Voice,' Kelly announced. 'You hit the button on yourself!'
Buzzer beater: John pushed Blake's buzzer and Don't Speak played again
'Dang it. Dang it,' Blake replied.
All of the judges seemed to be in lighthearted competition with one another as the show entered its third audition round at Universal Studios Hollywood.
Host Carson Daly, 46, personally tracked down the first contestant, Mendeleyev, 28, on the Venice Beach boardwalk in Los Angeles.

Mendeleyev's full name was Mendeleyev Galileo Einstein Pythagoras Darwin Euclid Leonardo Allan-Blitz, he revealed.
'My parents are hippies,' 'Lev' confessed, laughing. 'I was born in a bathtub, raised vegetarian, my mother's had purple hair my whole life. I don't wear shoes very often.'
His mother, Alison, had passed away from cancer the month before.

'It would have been Alison's real dream to have Lev reach the most people possible,' his father said. 'And The Voice is probably the coolest platform we could imagine.'
Lev's rendition of Bob Dylan's 1963 classic Girl From The North Country, to which his guitar was the only accompaniment, moved the judges—and had his dad and girlfriend in tears.
'I feel like your voice just sounds like the best glass of Pinot Noir ever,' said Kelly, comparing it to a warm blanket tucking her into bed.

'The tone was so rich and so beautiful and the story was just wrapped in your voice,' John agreed. 'I would love to coach you, Mendeleyev.'
'Say his name, Blake,' judge Gwen Stefani, 49, urged, making everyone laugh.
But 'Lev' went with John, the only one familiar with his idol, late folk icon Richie Havens.
Turned around Gwen was among the four coaches who turned around for the singer
Next up was Jake Hoot, 30, a missionary's kid from Cookeville, Tennessee, who grew up helping his parents and seven siblings start churches in the Dominican Republic.
Jake's love of music grew as he served as the choir director of those churches, but he moved back to the U.S. at age 20, where he had his daughter, Macy Lynn, 4.
'Macy's everything to me, so it's very scary to step away from all that and come out here and take the chance of doing this full time,' he relayed.
'I hope that when she is older she can look back and say, 'Well, Dad chased his dreams,' and maybe it'll inspire her to chase hers.'
One chair: Jake Hoot, 30, a missionary's kid from Cookeville, Tennessee, got Kelly to turn around
As Macy watched, the 6'6' Tennessean sang Luke Combs' 2017 hit When It Rains It Pours.
Kelly turned her chair, but Blake, paranoid, did not, thinking she had blocked him.
'I didn't even have to use my block,' Kelly marveled.
Like Jake, Calvin Lockett, 25, had a churchgoing background, being the son of two pastors.
The Voice was his 'big chance to become a secular singer,' the Durham, North Carolina, resident explained, going on to perform The Temptations 1971 hit Just My Imagination.
