According to an X Factor insider, the real reason Mrs O walked off Saturday night’s show was because she thought it was not fair that Kimberley was in the bottom two when millions of viewers missed out of even seeing her perform. "The show was advertised to run at 5.45pm on Saturday and instead started at 5.30pm,” our source pointed out – which is true. “So people missed Kimberley’s performance and Sharon thought that was unfair. She genuinely said enough is enough and didn't want to come back. She also blames herself for the wrong song choices and wanted to leave. ITV bosses have been begging Sharon to come back and she has said she will."
