Jennifer Lopez has admitted that she's not sure if she'll be returning to next year's American Idol.

The singer joined the judging panel in January with Aerosmith singer Steven Tyler after the departure of Simon Cowell and Ellen DeGeneres.

But the 41-year-old told Radio 1 DJ Scott Mills that she doesn't know if she'll be back on the talent show.

"I haven't been forced to make a decision and I'm glad about that because I'm on the fence," she said.

"I had an amazing time doing it and I loved it but I have a lot of other things happening.

"It's going to come down to making a choice of what I want to do for the next year. We're not really at the breaking point yet."

J-Lo's comeback single On The Floor made it to number one in the Official Singles Chart in April.

She's also released her seventh studio album Love?

Along with her music career, the singer and actress became a mother to twins in 2008 with husband Marc Antony.

She also made her Hollywood return last year in The Back-up Plan.

Lopez says her life can be a juggling act.

"In the beginning of my career it was busy all the time and I didn't mind. I was on my own, I was running around and doing all this for the first time. I loved it.

"But I didn't know how to say no. Now I'm a little more mature and I have a life with my family. You have to say no."
