Leona wasn't popular in the US either. Very few people watch the X Factor. To be honest, with situations like this it depends on the quality of the singer and their songs. And in the situation of Leona and Alexandra, the talent is definitely there.
I meant in the UK. Leona was huge in the UK which showed she had potential to break the US. Alexandra wasn't huge. JLS were the ones put forward to try and break the US.
PROMISE THAT WE'LL NEVER FALL APART
AND I'LL LOVE YOU WITH MY GLASSHEART
