ARIANA GRANDE
The singer’s debut performance of the ballad about her exes, “Thank U, Next,” was nearly flawless, except for one small, literal misstep: On Wednesday’s “Ellen DeGeneres Show,” the pop star briefly danced on a chair in high-heeled over-the-knee boots and tripped while trying to dismount. “Oh, my God!” Grande let out before returning to the mic. Seemingly able to find humor in the moment, she later let out a giggle.
