Adele might have had a hugely successful night in terms of Grammy Awards, but it seems that the shindig is a bit of a jinxed night for her in terms of performances.

Last year she was criticised for being out of key after undergoing 'audio issues' during her performance of 'All I Ask', and at last night's ceremony - during which she paid tribute to George Michael with a haunting orchestral version of his song 'Fastlove' - she experienced difficulties once again.

Stopping midway during the song, she realised she was in the wrong key and said 'I know it's live TV, I'm sorry, I need to start again. I fucked it up, I can't do it again like last year. I'm sorry for swearing and I'm sorry for starting again - can we please start it again?" before adding "I'm sorry, I can't mess this up for him!"
