Gary Barlow has threatened to quit 'X Factor' if Geri Halliwell comes back.
The former Spice Girls singer was a stand-in judge during the audition stages of the ITV1 show but permanent judge Gary was not impressed with her performance and can't see her ever returning.
He said: "She's crackers. How you see her on TV is exactly how she is in real life. The crowd really didn't like her. She got booed all day long. She was a bit over-excited.
"She'd been told she was auditioning for the role and, bless her, I think she tried a bit too hard. I do love her for being her though, we had fun backstage. She's sweet but mad."
"I doubt she'll be back though. And if she is, I may be going."
However, the Take That star says he was impressed with Geri's former bandmate, Mel B, and thought she made a great guest judge.
He told The Sun newspaper: "Mel was brilliant. It actually gave me a bit of a holiday the day she was there.
"I'm normally the one who delivers the bad news but she was doing it all so I could just sit there, going, 'Oh, that's awful, what she said' but secretly loving it."
