X Factor favourite Ella Henderson makes a surprise exit

X Factor favourite Ella Henderson has made a surprise exit from the show after losing out to James Arthur in a sing-off.

The pair had found themselves in the bottom two after the public vote.

After her last act left the show, judge Tulisa Contostavlos, said on ITV2's Xtra Factor: "I don't know what's gone on. I'm shocked."

Tulisa also said she was disappointed that Gary Barlow's final act Christopher Maloney is still in the show.

On Saturday night's show, Henderson received praise from the judges after she sang a slowed down version of the Grease classic The One That I Want.

Gary Barlow told the 16-year-old singer that she had just put on her "best performance to date by far", while Louis Walsh exclaimed she was "electric", adding: "You are going to sell millions and millions of records Ella."

There are now no remaining females left in the competition.
