When King asked Buttigieg three words that would best describe him, he exclaimed, "Standing near Lizzo, right now!"

The 31-year-old Grammy Award nominee replied she was "glamorous, talented and booty-ful" when King posed the same question to her.

When King then inquired if Buttigieg had taken any DNA tests recently — a reference to a line from Lizzo's hit song, in which she sings, "I just took a DNA test, turns out I'm 100 percent that bitch," — the Oval Office contender had a response at the ready.

"Yes, and I am 100 percent that nominee to lead the way to the future," Buttigieg, 37, said to laughs.

The morning show's hosts expressed nervousness about where Buttigieg was going with his quip.

"This has never happened before: the mayor and Lizzo at the same time in the room," King said. "I love it!"
