Adele seemed like she handled her Grammy performance troubles pretty well, tweeting afterward that "s--- happens" and noting that she was "treating myself to an in n out" as a result, "so maybe it was worth it." But in a clip from Thursday's Ellen DeGeneres Show, the singer reveals how she was really feeling. She explained that sound check went well, but "during the changeover in the ad break the microphones fell onto the piano strings, which was what the guitar noise was. Some people thought it was Bieber rehearsing but it wasn't him—we're on great terms." She added that she knew immediately what the problem was, because she knew the piano was double mic'ed, and wanted to turn around and fix the mic, but "froze."
"I'm always a bit pitchy anyway," she joked. "I am! It's emotion. When I'm flat and I'm sharp, I'm just emotional." But, she said, she was "embarrassed" about the whole thing and wanted to explain what really happened. "I cried pretty much all day yesterday," she said. "I kept, like, spontaneously bursting into tears." She noted that, in addition to the burger afterward, she also had a beer. The good news? She gets nervous before performances, but now "I don't feel like it could go that much worse than the Grammys, though, so I feel like I'm alright now." If she experiences sound problems again, she said, she would halt the performance and start over. (See the performance here.)
