Just two days on the job, pop queen Britney Spears is proving to be a popular judge on the “The X Factor.” She's also growing into her role as critic on Fox's singing contest show. “The X Factor” staged its first auditions for the upcoming season Thursday and Friday in Austin. And judging by the boisterous cheers and the “I love you, Britney!” calls from the crowd, the Grammy-winning singer is already a hit in her new role. She is also showing that she's not afraid to vote against contestants or disagree occasionally with show creator Simon Cowell and fellow judges Demi Lovato and L.A. Reid. Spears, 30, was brought in to help boost ratings for “The X Factor” after its debut season fell short of Cowell's predictions.
