Did Britney walk off 'X Factor' set?

Britney Spears is refuting reports that suggest she walked off "The X Factor" set after a contestant performed a pitchy version of her hit "Hold It Against Me."

"#Britneywalksoff??? LOL was just taking a little break people. I am having the BEST time!!!" the singer tweeted on Thursday.

Prior to her clarification, Spears wrote, "Texas has a lot of talent -- seriously! Loving @TheXFactorUSA auditions so far..."

A source close to the show told People Magazine: "[Spears] was not upset. She just took a short break, which is not uncommon for judges to do in these taped shows."

It seems Spears' fellow new judge Demi Lovato also appeared to have a good time at the Texas auditions.

The actress poked fun at Simon Cowell, calling him "grandpa" at one point, according to E!

Even fellow judge L.A. Reid wasn't safe. He tweeted: "Day 1 @TheXFactorUSA and I have already been cut to shreds by @ddlovato. Let the games begin!"

Spears and Lovato replaced former judges Nicole Scherzinger and Paula Abdul.
