The couple recently made the cover of a tabloid magazine, which reported that Shelton's alleged affair with a 23-year-old artist had shaken up their "perfect marriage."
“The Voice” coach took to Twitter on Sunday to address the rumors. He jokingly wrote, "Hey @mirandalambert… I just read in a tabloid that our marriage is falling apart! FOCK!"
Lambert quipped right back, tweeting, "Oh no! Can't wait to read if we make it or not,” to which Shelton heartily replied, "Ba! Ha! Ha! You see y'all! I'm making her funnier!"
Country superstars Blake Shelton and Miranda Lambert know how to poke fun at rumors that say they're splitting up.
