POP diva Whitney Houston's comeback appearance on The X Factor last night was marred by an embarrassing wardrobe malfunction with her frock.

Judges Simon Cowell, Cheryl Cole and Dannii Minogue gave her a standing ovation when she finished - but Sun readers phoned in to call the performance "appalling"
