Why did Simon Cowell tell Britney off at the start of X-Factor? Wed-29-Aug-12 16:51 Share this By MeganBritney’s hotness on X-Factor is supposedly because of Simon Cowell. Simon growled Brit after she turned up to an early taping not wearing a bra. He apparently told her she needed to clean up and dress more appropriately, and he insisted she always wear make-up and have her hair done before the show. Most girls in her position would demand that kind of thing, wouldn’t they?A source says:"It was made clear she is expected to be impeccably dressed and made-up for the show. And none of those ragged hair extensions."Simons reps however deny that conversation happened, probably cause it makes him sound like a bit of a D-Bag.
