Britney Spears has pointed the finger at fellow US X Factor judge Demi Lovato after being accused of "storming" off set during an audition.

Britney denies walking off in a huff

The audition, which fellow judge LA Reid described as "just horrible", involved a contestant in drag attempting to cover Spears' hit (You Drive Me) Crazy and resulted in the three judges walking off the set.

Spears denied storming off set and claimed she was "following" the 19-year-old judge Demi. The 30-year-old singer said: "I was taking her lead. She was like, 'Let's go,' and I was like, 'Okay'."

Spears added: "It was our break anyway. It was dinner."

Lovato explained they had all found the audition uncomfortable to watch because the singer had been given false hope by the audience's cheers.

She said: "I felt really uncomfortable, and I had to walk away. He [thought] that [he did] such a good job, and I felt so bad. I laughed at first, but I felt really bad."

Spears confessed she finds it difficult to watch certain contestants, admitting: "I usually can't look when they're bad. I can't look. It's really hard to tell some of them no."

She revealed that she prefers to adopt a kind and considerate judging style, explaining: "It's about using constructive criticism."

Spears did, however, agree that there have been times when she has been "blown away" by the talent on the show:

"It's really nice to come to a place like this and see so many special, talented people... I'm very impressed."
