The actress - who has a six-year-old son, Henry, from her previous relationship with director Darren Aronofsky - tied the knot with Daniel in June 2011 and admits the most important thing in her life is her family.
Rachel told the Daily Mirror newspaper: "It`s the thing that matters the most to me. It`s incredible watching my son growing up, leaning to read and discovering the world.
"Being a mum is the greatest joy of my life. And I love beingmarried - I`m very, very happy."
Rachel, 42, fell for the James Bond star on the set of `Dream House` in 2009 and was finally able to show off her newfound stunt skills to action flick veteran Daniel when he visited her on the set of spy thriller `The Bourne Legacy` in the Philippines.
However, the actress did rely on some tips from her co-star Jeremy Renner to make her action scenes look convincing.
Rachel said: "I had to try not to run like a girl. Jeremy told me that girls` hips are wider so our feet turn our when we run, so I was concentrating on not running like that."
