Simon Cowell: Britney Spears didn't walk off "X Factor" set

(CBS News) After reports surfaced that pop star Britney Spears had stormed off the "X Factor" set, fellow judges Simon Cowell and Demi Lovato stepped in to defend the pop star.

In an interview, the two used humor to quash what they called the rumors about Spears.

"No, that was Demi," Cowell said, according to a report in  E! News. Lovato responded, joking, "I was like, you know, tired of Simon, So 'I had to just, like, go.'"

Cowell then answered the question honestly on the show's website, reports E!, saying, "There was no walking off."

"We have breaks every 5 or 6 songs. You can go have a cigarette, you can go to the loo. SO as soon as anyone left their chairs, it was reported...that someone had left the show - and they hadn't!"

Spears even responded to the rumors herself on Twitter saying, "#Britneywalkoff??? LOL was just taking a little break people. I am having the BEST time!!!"
