Adele 'Cried All Day' After Grammys Glitch

Adele has revealed she "cried all day" after her performance at the Grammys was hit by sound issues.The British star was singing her hit All I Ask from her new album, 25, when the sound dropped in and out and she sounded uncharacteristically off-key.
She tweeted to explain the technical hitch: "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."
On Wednesday she told The Ellen DeGeneres Show she wanted to tell everyone what happened straight away because there was a lot of confusion.
There had been some reports that the interference was caused by Justin Bieber rehearsing but Adele quickly dismissed this.
