She is amazing at singing live. She actually sounds better live which I can't say about others. She looks great too.

I think she's the best singer the X Factor has ever had.

Well technically Alexandra, Leona, Brenda, Nicki, Danyl, Joe and loads more are better at singing than her but I can see why a lot of people prefer her voice. Her voice tone is unique and there's something so cool,natural and amusing about the way she sings live. I love Alexandra, Diana and Leona's voices equally, they all bring something different to the table.

Leona and Alexandra are possible the best vocalists from the X Factor, but I just think Diana is different, which I think is what the pop world needs right now. But I get what you mean, I agree

I love her voice! I am a new fan!
