After the technical difficulties that plagued her high-profile Grammys performance, Adele has revealed that she “cried pretty much all day” afterwards.

In an interview on ‘The Ellen DeGeneres Show’ on Thursday (February 18th), she told Ellen that the strange sounds that could be heard throughout her rendition of ‘All I Ask’ during Monday night’s awards show were because of microphone problems that couldn’t be put right on the spot.

“During changeover and the ad break, the microphones fell onto the piano strings, which is what the guitar noise was – some people thought it was Bieber rehearsing but it wasn't him,” she said wryly. “And it just kinda put the whole thing off, really.”

She explained that she immediately knew something was wrong, but was completely unable to do anything about it.

“I knew where the mic was and I wanted to turn around and lift it up, but I froze,” she continued. “But I actually felt like it went well… I'm always a bit pitchy anyway.” The audience expressed disbelief, but she said self-effacingly “I am, it's emotion, it's emotion, when I'm flat and I'm sharp I'm just emotional!”

About the aftermath of the performance, she said that felt “so embarrassed” and admitted that it hadn’t done anything to ease her nervousness before performances, which she “still” feels despite being the most successful artist in the world last year. She was recently named the top-selling artist globally with the release of her third album 25 three months ago.

“I cried pretty much all day [Tuesday],” she said. “In fairness, I would've cried if it had gone really well as well… I kept spontaneously bursting into tears yesterday but it was all right, I'm fine.”
