Simon Cowell is personally defending his new X Factor judge Britney Spears from a second report that the pop singer walked off the set.

On Friday, Us magazine reported that a set source said, "After a very popular contestant finished, Brit stood up and immediately walked towards the tunnel where judges enter. Her bodyguards and entourage jumped up and ran after her. She was moving fast . . . It was odd."

But the idea that she'd "walked off," is just plain "rubbish," an X Factor spokesman said later.

And Simon Cowell echoed this sentiment, later telling reporters: "There was no walking off! We have breaks every five or six songs. I have to say I like this panel. They are very opinionated, like all to talk a lot."

Britney's first alleged "walk off" was on Thursday, but as Breaking Celebrity News exclusively reported, when all the judges took a break, Brit was gone from the judges table 15 minutes longer than the rest.
