Gaga then stunned the show's judges by leading Kitty back to her dressing room to give her a cup of tea and some advice on how to launch her career.

A show insider said: "Gaga couldn't believe Kitty had been axed and thought she was one of the most talented and exciting acts in the competition.

"She thought that Kitty had been misunderstood and it reminded her of her own struggles to be accepted."

Kitty, 27, was axed when the judges voted her off following a sing-off with Misha B.

But as their verdict sank in, sobbing Kitty snatched the microphone from host Dermot O'Leary and sang an unaccompanied chorus of Gaga's hit Born This Way.

Gaga — who earlier performed her single Marry The Night after emerging from a mausoleum dressed as a decapitated corpse — responded by dashing onstage.


They fired off scores of Twitter messages blasting the impromptu performance, with one branding it "cringeworthy".


The show's judges seemed equally bemused by Gaga's antics. Gary Barlow said the star was "on another planet."

He added: "The way she ran on there. That is a world-class superstar right there."

Kitty was voted off after performing Over The Rainbow. Rival Misha sang Jessie J's Who You Are.

Louis Walsh, Kitty's mentor, chose to save her. But Gary, Tulisa Contostavlos and Kelly Rowland all picked Misha.

But backstage, Tulisa and Kelly have been less supportive of Gary — blaming him for a series of blunders that have made this year's contest shambolic.

After Saturday's show, Tulisa collared Gary by his dressing room and told him to "put his ego back in the box." A source said: "Tulisa laid into Gary."
