The Oscar-nominated actress and singer believes she works too hard and is keen to have a family at some point in the near future.
Asked about where she would like to be in 10 years time, the 40 year old said: "On cruise control, with a couple of kids under my belt. It`s in the Lord`s hands.
"I work a lot. I want to make sure I-m living life to the fullest and checking in with me."
The Hollywood star also has advice for British royal bride Kate Middleton, saying she needs to find a "sanctuary" of her own because so many people will be interested about her relationship with Prince William.
She told Parade.com: "Make sure you have a sanctuary, because everybody in the world is going to be in your business. He happened to be born a prince; you happened to go to college and meet him.
"You`re two kids who fell in love. I just hope you have a happy life. And don`t take anything personally."
