Jennifer Lopez may come back for a second year as a judge on American Idol. Or she may not. "You know, this is the question of the hour. I don't know, I don't know," Lopez said yesterday in an interview with the BBC. "I had an amazing time doing it and I loved it but I have a lot of other things happening and it's gonna come down to making a choice of really what I want to do for the next year." Lopez and fellow new judge Steven Tyler have been credited with bringing a gentler attitude to the top-rated show following the departure of Simon Cowell. (More Jennifer Lopez stories.)
