Duffy has opened up about her struggles with fame after her 2008 debut album ‘Rockferry’ catapulted her to the top of the charts.

The Welsh singer, who sold 6.5 million copies of her debut worldwide, says that the constant work she had to do kept her wanting for companionship.

She said: "I was living out of a suitcase and always flying here and there. It was everything I'd ever dreamed of but there were times when I found it hard. I love my music and performing but some of the other demands terrified me. I am just a normal girl from Wales and always will be.”

"Once in America I locked myself in my room and cried and I'm not that kind of girl,” she told The Sun. “I am quite tough and can cope with almost anything but that time was horrible. I just wanted my mum with me.

"I remember feeling as though things were going to fall apart. I don't know if it was a borderline breakdown - but it was a hard time."
