Superstar Mariah Carey battles against racism wherever she travels, because people forget she is mixed race.
The singer was born to an Irish-American mother and an African-American father.
She says, "I'm in a room a lot of times with only white people, and they forget and say things that are offensive - and I have to put them in check. And I'm sitting there and I'm thinking I'm either going to have to leave or I'm going to have to talk about it.
"After travelling the world, I think racism, or ignorance, is everywhere. It's in the US, Italy, France. Even in certain Latin American countries, where it's a very mixed society."
