Rachel Weisz leads an "ordinary life".

The Oscar-winning actress, who has three-year-old son Henry with director fiancee Darren Aronofsky, admits her home life is ordinary despite being in a showbiz relationship.

She said: "Of course, it's not ordinary to get dressed in frocks to walk down red carpets and travel all over the world and stay in five-star hotels.

"I'm not working in a factory. But I drop Henry off at school, I pick him up. I try my hardest to keep everyone together.

"I am interested in playing extra-ordinary women, but I have an ordinary life."

The 40-year-old Brit also admits she loves acting because there is always a new project for her to get involved in.

She told Culture magazine: "That's the great thing about acting. I can never imagine being satiated. It's just like some math problem to figure out. I'm just getting started."

Recently fellow British actress Gemma Arterton admitted she wanted to have a career like Weisz's, saying she admired the variety of her roles.

She said: "I'd really like the type of career Rachel Weisz has. I have a lot of respect for her, brilliant, talented, intelligent, a witty sort of woman. You know, she'll do a rom-com - not that I ever want to do a rom-com - but then she'll go off and do 'The Constant Gardener', have a family and live quite a normal life, it seems. I respect that."
