X Factor contestant Honey G was visibly shaken when a member of the audience ran on stage during her judges' feedback on Saturday night's show.
The controversial act had been performing MC Hammer's U Can't Touch This and was waiting to hear what the show's mentors thought of her efforts when the stage invasion happened during Louis Walsh's comments.
Honey G looked startled by the man, who tried to touch her as he rushed the stage, but head judge Simon Cowell was quick to jump to his feet and check that she was all right as the man was escorted from the stage.
Simon said: "I thought that was part of the act for a moment. That's what you create, people go crazy for you. You've got a second song to come, don't let that throw you."
Her mentor Sharon Osbourne said: "Your fans want to touch you, even more so when they're not allowed to."
Honey G looked upset by the incident and appeared to be struggling to concentrate on the judges' comments about her performance.
Host Dermot O'Leary said: "Obviously we had a stage invasion, three punks thought they could come on and take on Honey G, but could they?"
She replied: "I don't think so."
The programme also experienced a stage invasion in 2009 when DJ Calvin Harris stormed the stage with a pineapple on his head while Irish twins John and Edward, better known as Jedward, were performing.
