Natalie Portman says her style has changed since becoming a mother. The Oscar-wining actress welcomed son, Aleph, into the world last June and admits she has had to adapt the way she looks as she is keen to appear more mature.

"I've been trying to look more like a lady recently. I used to be happy in a T-shirt and sweatpants, and now I feel like I want to make myself a little more grown-up - now that I'm a mom," she said.

The 30-year-old beauty also says she loves vintage fashion because there's always a story behind the outfit. "I feel like you are sort of stepping into history. It's really amazing to get the story of where a dress has been; you know that it has lived through many people's stories," she told WWD.
