X Factor's "golden goddess" Ella Henderson stole the show tonight with a simple and slowed down version of the Grease classic The One That I Want.

The last girl in the singing contest stood out during the seventh live studio round - celebrating guilty pleasures - with the four judges all in agreement about her singing talent.

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."

Nicole Scherzinger complimented Henderson on her shimmering dress, saying: "You look like a golden goddess."

Receiving similar praise was former Asda worker Jahmene Douglas after his rendition of the Harold Melvin track Don't Leave Me This Way.

"You have got it all," Walsh told him.

Tulisa got deep with her post-performance comments, saying he has become more of a man as the competition has progressed.

"You have just evolved into the man you are meant to be," she said.

In an unusual move by an X Factor judge, Barlow, who mentors Christopher Maloney - the only act left in the overs category - told Scherzinger's act James Arthur that he was rooting for him to win.

"Putting my category aside - I probably shouldn't say this - I want you to win this competition," he said.

Scherzinger described Arthur as simply "mesmerising" after his performance of Lauryn Hill's Can't Take My Eyes Off You.

The former Pussycat Doll's other act, Rylan Clark, caused a stir with Barlow, as the Take That frontman criticised his performance of When Will I Be Famous.

He said: "The good news is - you're famous. The bad news is - give you a couple of months..."

Turning to Scherzinger, Barlow added: "It's got to be over now surely?"

Clark took the opportunity to defend himself, claiming that famous stars with his style of performance choose to mime so they can dance energetically and entertain audiences.Barlow shot back: "In future, mime."

Union J, who found themselves in the bottom two last Sunday night with fellow boyband District 3, were told by judge Tulisa that they had "good energy" but were "too cheesy".

The group sang Carly Rae Jepsen's Call Me Maybe and judge Barlow advised the boys: "Keep your eyes on the prize."

Their mentor Louis Walsh supported his boys after their performance, saying "they could be the next big boyband".

In reference to their seeing off of District 3 last week, he added: "You've won the battle of the boybands."

Taking on the Bonnie Tyler classic Total Eclipse Of The Heart, Christopher Maloney was told his performance was "a little creepy" by Scherzinger, while Tulisa told him she thought he "sounded really good".

Speaking about Maloney, Barlow said: "I need to tell everybody what a fantastic guy you are to work with."

An act will leave the competition in Sunday night's result show.
