"I don't plan to keep acting very long, I'm ready to do a few things now and fade away and get ready to be a grandma one day," the Hoolywood movie star told the British broadcaster in an interview posted on the BBC website yesterday.

Jolie and her partner actor Brad Pitt have emerged as a Hollywood power couple, and together they have three biological children and three adopted children.

She says her new film helped her get pregnant.

She said: "I got pregnant right in the middle of shooting and I think partially because of the film. I was so emotional about children that I think something in me kicked into gear."

Angelina also admitted she considers her ever-expanding brood in everything she does, adding: "The centre of my life is my kids."

The 33-year-old actress - who raises six children with partner Brad Pitt - believes she wouldn't have conceived twins Knox Leon and Vivienne Marcheline if she hadn't starred in new movie 'Changeling', in which she plays a mother whose son goes missing.

In response to a question about whether she will give herself a "cutoff point" for acting, Jolie said she would make no pledge to completely stop acting.

Jolie, who stars in the movie "Changeling" from director Clint Eastwood, said she has not worked on a movie for a year. Apart from starting a project in February, she said that she will probably not work again for another year.

"So maybe it will be once a year and then maybe it will be once every three years, and then just naturally -- I like being home a lot these days," Jolie told the BBC.

Jolie, who earned an Oscar for her supporting role in the 1999 movie "Girl, Interrupted," would not be the first actor to talk of walking away from it all at a young age. Last month, "We Own the Night" star Joaquin Phoenix, 34, said that he was retiring from acting to focus on making music.
