When I was growing up, hip-hop was still a pretty specialised thing.

I am a black British female artist, so I must be like Ms Dynamite, I must be like Shystie, I must be like Jamelia, but we're all different.

I'm the female Jay-Z. I never compared myself to other women artists. I compared myself with the best, and the best is Jay-Z.

When my career slowed, I knew deep down it wasn't over.

Opposites may attract, but I wouldn't put my money on a relationship of financial opposites.

In a globally interdependent world, a better financial and investment system cannot be achieved on a country-by-country basis. There may be no one-size-fits-all model for economic development, but without global standards and complementary regulations, the long-term outlook for the world economy will remain bleak.

I try to do the right thing with money. Save a dollar here and there, clip some coupons. Buy ten gold chains instead of 20. Four summer homes instead of eight.

My Vegas act is how I make my money.
