The superstar singer performed 'All I Ask' at the annual ceremony in Los Angeles last night, but a technical error beyond her control affected the sound.
She told fans: "The piano mics fell on to the piano strings, that's what the guitar sound was. It made it sound out of tune. S**t happens."
And staying upbeat and showing why we all love her so much, she added tythat she was off to indulgent in a takeaway burger: "Because of it though... I'm treating myself to an In n Out. So maybe it was worth it."
We reckon she still sounded INCREDIBLE.
Meanwhile, a rep for CBS, the US network that airs the Grammys, added there had been a five to eight second technical issue durin teh show that was out of its control.
