My parents divorced, and I didn't have much of a daddy growing up.

Consumerism diverts us from thinking about women's rights, it stops us from thinking about Iraq, it stops us from thinking about what's going on in Africa - it stops us from thinking in general.

I'm very involved with PETA - People for Ethical Treatment of Animals - and Greenpeace and a lot of women's shelter and clothing giveaways.

I wanted to do it my way with my career, and I had this arrogant notion that people weren't just interested in my music but me as a person. That was my bit of arrogance, I guess. That's something I learned from Madonna. I was a fan right from the first time I heard 'Holiday.'

I put my career in second place throughout both my marriages and it suffered. I don't regret it. You make choices. If you want a good marriage, you must pay attention to that. If you want to be independent, go ahead. You can't have it all.

Much as I'm loving the 'Strictly' experience, I'm sure I'll always be better known for my business career and my appearances on 'Dragons' Den' than I will for my cha-cha-cha or Viennese waltz.

There are so many talented young actors in the industry. I'm just happy to have a job!

I think Uber is just very different; there's no model to copy. It may be the reason why we've been a lightning rod in so many ways, because we don't do anything conventional... And then I think also, as an entrepreneur, I'm a bit of a lone wolf.
