LONDON (AP) -- 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 Tuesday in an interview with Scott Mills of the BBC.

Lopez and another new judge, Aerosmith frontman Steven Tyler, brought a gentler attitude to the top-rated show following the departure of Simon Cowell.

"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 said.
