James is now 14, but his mum still remembers every second she spent in the delivery room back in October, 2002.

"If I could revisit one moment in my life, it would be the birth of my children, definitely," she tells The Edit. "I only got to give birth once. James is like, 'Why do you always want to talk about that?' I'm like, 'Because it's the greatest!'

"There is this suspended animation around it (birth): everything goes away; the entire world is sucked up; time suspends. It's just you and, in my case, my husband, and this child, and it's absolute euphoria."

The actress, who is also mum to six-year-old twin girls born via a surrogate, also tells the magazine she and her husband Matthew Broderick have abandoned plans to leave New York City, because their kids love the Big Apple.

"I can't imagine living anywhere else," she explains. "I mean, Matthew and I do think about it, we look. We just don't do it. We stay.

"I used to think we were selfish, but when we came back to New York after the summer break this year, I asked my daughters, 'Would you prefer it if we had space?' And they said, 'No!'"
