"I haven't been forced to make a decision, and I'm glad about that because, honestly, I'm very on the fence about it," she said in an interview on BBC Radio 1.
"I had an amazing time doing it, and I loved it, but I have a lot of other things happening," she said.
"And it's going to come down to me making a choice of what I want to do for the next year and we're not really at the breaking point of 'You have to make a decision right now!' "
FOX News reported in May that the 41-year-old, who boosted ratings and attracted rave reviews when she joined the hit TV show this season, earned significantly less money from the show than fellow judge Steven Tyler.
Tyler, who is tied into a multi-year contract that ensures he will return through the 11th season alongside original judge Randy Jackson, reportedly raked in $18 million for his first season alone.
FOX is owned by News Corp., which also owns NewsCore and the New York Post.
