Destiny's Child have revealed reforming after a three-year break was a stress-induced 'nightmare'.
Beyoncé Knowles, Kelly Rowland and Michelle Williams admit being together in a studio after so long was tense - and their songs initially sounded 'really bad'.
The threesome got back together earlier this year, after pursuing their own solo projects, to make new album Destiny's Fulfilled, out next month.
Beyoncé revealed: 'We had two studios set up at the same time. The way we recorded the album was very different. We got sent thousands of tracks from different producers - but after picking out 30 we liked - they all started sounding the same.'
The girls began to grow despondent as they set about writing their own songs - and they started to believe they would never produce a successful album again.
Kelly said: 'Some days I was like, 'What are we doing? This is not a good song. Let's go to the next.' I had to calm down because I was so anxious. All of us were.'
