is moving her children Joe and Mia back to the UK while her estranged husband Sam Mendes films the new James Bond movie.
The Oscar-winning actress - who announced she was splitting from the director in March 2010 - thinks it wouldn't be "fair" to deprive him of seeing his seven-year-old son and 10-year-old stepdaughter from a previous relationship
and will take them to London so he isn't far from them.
Kate - who currently lives in New York City - said: "Sam is doing the next Bond film, all being well, and we'll all be in England if that happens.
"It's such a massive commitment for him and it's not fair for him to commute backwards and forwards to New York from London. It would be impossible. The children will be there with me."
Discussing their split, the 35-year-old British screen beauty
insists she and Sam are still good friends who have a lot of "respect" for each other.
After he makes the James Bond adventure, Kate could even see her working with the 45-year-old filmmaker again, following the critical success of their 2008 movie 'Revolutionary Road'.
She added to the Daily Mail newspaper: "I can see us working together again - that's the way it is.
"We're really good friends and have very good respect for each other. I can see it, but you'd have to ask Sam what he thinks."
Last month, Kate called time on her relationship with model Louis Dowler after four months of dating, reportedly thanking him for helping her get over her split with Sam.
