British singer Adele says she cried the day after a technical mishap on the Grammy Awards telecast Monday caused a rhythmic clanging and a few seconds of low-volume vocals as she performed “All I Ask.”

“I cried pretty much all day ,” the 10-time Grammy-winner, 27, told daytime host Ellen DeGeneres on the talk show’s broadcast Thursday. “But the thing is, in fairness, I would’ve cried if it had gone really well,” she said. “If it’d been a standout performance, I would have cried as well. I always cry. But I kept, like, spontaneously bursting into tears for no reason. But it was all right . . . I was fine.”

In fact, “I treat myself to a burger. And a beer,” she said, adding detail to a tweet Monday night where she wrote that, “Because of . . . I’m treating myself to an in n out,” referring to the In-N-Out Burger chain.

The Grammy pre-show sound check had gone “really well,” she told DeGeneres. “And then during the changeover and the ad break, the microphones [in the onstage piano] fell onto the piano strings, which is what the guitar noise was.

“Some people thought it was [Justin] Bieber rehearsing, but it wasn’t him,” she joked.

She went on to explain, “I knew what it was, because in rehearsal on Saturday, [the sound crew said] ‘All right, we’re going to double-mic the piano in case one of them doesn’t work.’ And I knew where the mic was and I wanted to turn around and lift it up, but I froze.”

Had it happened during a concert performance, “I would’ve busted a joke,” she said. “But because it was TV, that’s why I couldn’t make it my own. I couldn’t make the disaster my own!

“Next time I will,” she vowed. “Next time I have any sound issues, I am gonna stop — ‘Sorry, that’s not working for me. If we have time to do it again, let’s do it. Otherwise, bye.’ ”
