Sinitta has suffered a wardrobe malfunction while posing for pictures on the red carpet at X Factor musical I Can't Sing!.
Simon Cowell's right hand woman turned up to support him at the Harry Hill created musical, wearing a dramatic red gown with a plunging neckline and a high-collared snakeskin jacket, according to the Daily Mail.
But when she took the jacket off to pose for photos alongside X Factor judge Louis Walsh, Sinitta didn't realise that she had fallen out of the front of her dress and was exposing herself to the cameras.
Luckily, an embarrassed Sinitta soon noticed the boob she had made and saw the funny side, covering herself up and laughing with Louis who was in hysterics.
The musical, which was financed by Simon Cowell and created by Harry Hill, pokes fun at Simon's ITV singing contest with characters based on him (played by Nigel Harman), Louis, returning judge Cheryl Cole and presenter Dermot O'Leary.
Other guests at the premiere at London's Palladium included Amanda Holden, Kate Beckinsale, David Walliams, Stacey Soloman and Rylan Clark.
