"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.

"I haven't been forced to make a decision and I'm glad about that. Because honestly, I'm on the fence about it," adds the 41-year-old mother of twins, who is making her promotional rounds in Europe for her new album, "Love?"

Lopez and fellow new judge, Aerosmith frontman Steven Tyler, brought a gentler attitude to the top-rated FOX 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.
