Last week, Robbie Williams raised a few eyebrows when he bounded onto the X Factor stage looking as if he'd indulged on 25 Red Bulls too many (for the record, he was just extremely excited), but this week that was all forgotten, after Whitney Houston took erratic to a new level. Not only did Whitney's dress bust apart midway through her performance ("I sang myself out of my dress," she told Dermot afterwards), but she also seemed to struggle to answer any questions at the end. There's no doubting that Whitney looked absolutely amazing, but her vocal performance didn't quite hit the right note for some of us. Peter Andre was watching at home and Tweeted, "There is only one big W, but tonight I'm not sure...just being honest." Dermot did his best to get some comments from the diva, but she made it pretty clear that none of the contestants had impressed her very much, instead urging them to "practice, practice, practice". We do love The Whit, but this was definitely not her finest hour. Have a watch and tell us what YOU think...
