During the interview Rebecca also revealed how touched she was when Prince William told her a surprise secret upon meeting him in Shanghai last year.
"I was the poor kid growing up, I had a tough upbringing," she said. "So when I met Prince William that was so special to me. I really had to have a moment and take that in.

But the song and the album of the same name were not easy for Ferguson to write – and are even harder for the X Factor star to talk about because the inspiration is “so personal”.
“I had quite a bad time with what I wrote Superwoman about,” explains an emotional Ferguson. “It’s so personal. It’s so hard to speak about.
“I found out I was pregnant. I had my beautiful little girl, Arabella, and there was a relationship breakdown.
“At one point, I was really depressed and people were trying to get me out of bed and I couldn’t.
“I needed to hear a song or something that could help me. So I decided to make an album that would hopefully encourage other women who were going through similar situations, inspire them and help people who are feeling down to feel better.
“They can press play and think ‘you know what, if Rebecca can get through it, I can get through it’."Being a woman is a powerful thing and I intend to use my womanhood to change the world".
She has also received comparison to Aretha Franklin, and won critical acclaim for reinterpreting the Billie Holiday songbook in her previous album Lady Sings the Blues.
