Watts: 'I didn't think I'd have kids so late'

Naomi Watts has admitted that she never thought she would have children late in life.

The actress, who has two sons with partner Liev Schreiber, has revealed that despite motherhood being the "hardest" job, it is also the most "rewarding".

Speaking to Glamour, the 41-year-old said: "I didn't ever think I would be having kids this late. Then two under the age of two in diapers - it's the hardest thing I've ever done, but the most rewarding."

As for balancing her career while being a parent, she added: "I didn't really worry about having time off. My career started late, so by the time I was ready to have children, I felt like I had enough body of work under my belt. I was ready to say, 'Okay, let's slow this down a little bit'."

Watts recently revealed that she was forced to attend boot camp in preparation for her role as CIA operative Valerie Plame in Fair Game.
