Rosario Dawson will give up acting when she has children.

The Fire with Fire star - who is in a relationship with 55-year-old director Danny Boyle - wants to focus on "making the world a better place" when she eventually settles down to start a family.

"I won't be able to act anymore. I'll just be focused on trying to make the world a better place for my baby," she said.

The 33-year-old actress has also admitted she used to go to school in her pajamas and confesses her casual style hasn't evolved much since those days. "I didn't brush my hair; I wore platform flip-flops and Converse because I had a height complex. I would roll in wearing my pajamas, just in the nick of time before class started. And that's still me," she told Latina.

Rosario's relationship with Danny was revealed earlier this month, with the actress - who met the filmmaker on the set of his latest film Trance - even in attendance at the London 2012 Olympics opening ceremony, which the director masterminded.
