The `4 Minutes` hitmaker - who has children Lourdes, 13, Rocco, nine, Mercy, five, and David, four - admits she is so focused on raising her family and working on her forthcoming movie `W.E.` that she hasn-t the "time or energy" to make a record.
She said: "I haven`t really been focused as much as I should be on the music part of my career, because the movie has consumed every inch of me.
"Between that and my four children, I don`t have the time or energy for anything else."
The 51-year-old star admitted she has been so distracted by her other ventures, she doesn-t even know how her music will be released when she finally finds the time to record again.
She added to Interview magazine: "It`s weird. I don`t have a record deal right now with anybody. I don`t know how I`m going to get my music out the next time I make a record.
"I`m going to have to reinvent the wheel. For example, I do appreciate that lots of people worked long and hard putting together things like the DVD of the `Sticky and Sweet` tour that we just released, and I have seen the finished product, but I have got no idea how people are going to find out about it or how it`s going to be sold. I think I have a fan club- well, that`s what they say."
