"If the talent and the desire is there, I don't really think it matters what colour you are," she told Newsbeat and BBC Radio One. We don't live in the 1950s any more, we're in a multicultural country. So no, I think that's pretty far from the truth, look around and I think you'll see that it [Black Soul] really does exist."
