London, Oct 19 Pop diva Whitney Houston's comeback appearance on The X Factor was marred by a wardrobe malfunction with her dress.

Houston, 46, was clearly annoyed as she struggled with a loose strap on the long silvery dress she wore during the live performance of her new single 'Million Dollar Bill'.

The six-time Grammy winner, backed by a troupe of male dancers, pulled a face when she realised the strap was sticking out.

She later joked about the malfunction in an interview with host Dermot O'Leary.

"I sang my song out of my dress," the Sun quoted her as saying. (ANI)
