Whitney Houston and Cheryl Cole upstaged by John and Edward on X Factor

Fellow Girls Aloud members (apart form Nadine) turned up to support Cheryl Cole as she performed on X Factor last night (9/10 for outfit, 3.5/10 for performance). Whitney Houston was mentoring and also performing, but it looked like she was having whatever it was Robbie Williams enjoyed before his performance last week...

After all the 'controversy' over Cheryl not performing or singing live on the show, in the end she sang half of her new single live and mimed the rest (and we were thankful for that part). But did it really matter in that costume?

Meanwhile, Whitney sang her new single 'Million Dollar Bill' live but suffered a wardrobe malfunction half way through as her dress almost fell off and when Dermot O'Leary chatted to her after the performance, she didn't quite seem the full ticket.
