Natalie Portman wants to be a mother.

The 28-year-old actress feels she has grown up and is finally responsible enough to settle down and start a family.

The 'Closer' star recently played "strong" and maternal Grace Cahill in the war drama 'Brothers', alongside Tobey Maguire and Jake Gyllenhaal.

Natalie has reconsidered her views on motherhood since starring in the movie.

She explained: "It was such a fantastic opportunity because so many parts written for females my age are just like the cute, girlish love interest. To get to play a real woman who's really strong and a good mother was really a great opportunity. It was not that challenging to be mother-ish because I have the most maternal mom in the world. So I've had a role model for my entire life."
