Britney Spears scares contestant, and us, in new X Factor USA promo vid

We are a bit scared of Britney Spears after seeing this latest clip for X Factor USA.

In the clip Britney tries her best to convince us that she is a nice judge, saying:  "I feel like my judging style is very subtle."

However, she can then be seen looking one poor contestant up and down before asking: "I want to know who let you on stage."

Fellow judge Demi Lovato then sums things up nicely when she says: "That's the great thing about this panel — we're really honest."

That's one way of putting it.

It would seem Simon was right when he told reporters than Ms Spears has a dark side!

He said: "Britney's quite mean, as you'll discover."

One thing is for sure, we certainly wouldn't want to get on the wrong side of her!

Meanwhile, our very own X Factor starts this coming Saturday — that's tomorrow- and we could not be more excited!

We are expecting drama, amazing singing and even more amazing dresses thanks to judges' Nicole Scherzinger and Tulisa.

We went to the Press Launch yesterday and are still trying to work out which lovely lady's dress we like best.

We are think of this as Fash Off Round One, and Saturday as Round Two.

Ding, ding!
