X Factor: Whitney Houston comeback questioned after live performance

The 46-year-old soul diva, who has fought a public battle against drug addiction, made her first UK TV appearance in 12 years on Sunday night's programme.

She sang her single Million Dollar Bill, over some pre-recorded vocals, and suffered a wardrobe malfunction when a strap at the back of her long silver dress snapped open.
Questions were also raised about Houston's physical condition as she looked drowsy and did not speak clearly when being interviewed by host Dermot O'Leary.
Fans have inundated the show's official website to express their shock at the performance.
One fumed: "What a huge waste of her talent. People should watch and learn what harm one can do to ones self. I hope for Whitney and all her fans she gets a grip and rejoins this planet."
Another, using the name _kelcee_, said: "Not sure what was going on with whitney what a huge let down."

Her performance came a week after former Take That idol Robbie Williams sang his latest single Bodies in a wide-eyed and very heated performance.

X Factor judge Cheryl Cole also performed her new song Fight For This Love in the studio following a week of strong debate about whether or not she would sing live. Simon Cowell described her routine as "incredible".

Rikki Loney was evicted from the show this evening after losing out to Rachel Adedeji in the live head-to-head. Irish duo John and Edward Grimes won through to the next round of the competition but were booed vociferously by the studio audience.
