Brucknell lost in a sing off against Misha B and promptly burst into tears, grabbed the microphone and belted out a few lines of idol’s song.

Her pain was felt by X Factor guest Lady Gaga who gave her a hug and said: “Go get a drink”.

Brucknell’s dramatic departure was met with horror by Twitter’s army of X Factor viewers, who tweeted such gems as: “Someone shoot her now,” and “No Kitty,no”.

Meanwhile Amelia Lily was back on the show after being voted in to replace axed Frankie Cocozza. After singing Queen’s The Show Must Go On, Lily is now favourite to win the show – with Ladbrokes and William Hill giving her odds of 11/4.

With last week’s dramas propelling X Factor into the headlines, bosses were expecting Saturday’s show to see a hike in viewing figures, however plans were thwarted by a power cut at the BT Tower in central London.

An auditions round-up was screened while technicians battled to fix the technical hitch.

Problems were also rife on the show as a fight erupted between judges Tulisa and Gary Barlow.

Tulisa is said to have slammed Barlow’s “giant ego” after he called her group, Little Mix, “predictable”.

“His ego is out of control, isn’t it?” Tulisa countered. “Gary could have a party with his ego, he really could. We should have a birthday party just for his ego.”
