Not sure if I will be back for `American Idol 3`: Lopez

Los Angeles: Singer-actress Jennifer Lopez is not sure if she will be judging the upcoming season of `American Idol`.

The 42-year-old, who is the only female judge on the singing competition show, said she is so busy with the show that she misses doing other things, reported Aceshowbiz.

"I enjoy it. I really do enjoy it. Now this is my second year. I don`t know if I can go for a third year. It really does lock you down," Lopez said.

The actress raises two kids with estranged husband Marc Anthony said she also misses spending time with her children.

"Now they`re getting more mobile. They`re about to go to school. I just don`t know. I don`t know," she added.

Lopez also commented on the newly announced "The X Factor (US)" judges, Britney Spears and Demi Lovato.

"They`re both more than capable to handle it. I think they`ll have a good time. It`s fun - working with the singers and doing your thing and knowing what you`re talking about from experience and they both have that."
