No idea if Brian is back this year on UK X-Factor, but the person Raah was ra-ferring to is Grace Woodward, who was the stylist, and responsible for Weasel's helmet-of-hair and the ghost-frizz, amongst other horrors.
She also dated Matt Cardle for a bit, was a judge on Britain and Ireland's next top model, and slagged off Alexandra Burke on Twitter recently. And I can confirm to you that she is indeed, a prize bitch.
