Motherhood toughest job ever, actress Naomi Watts

London: Hollywood actress Naomi Watts has claimed motherhood is the "hardest thing" she has ever done.

The 44-year-old actress, who has sons Alexander, two, and Kai, 18 months, with long-term partner Liev Schreiber, didn`t plan to have children late in life and thinks their closeness in age makes raising them extra difficult, but doesn`t regret her life`s decisions, reports a news website. "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," she said. Naomi didn`t find acting success until she was cast in "Mulholland Drive" aged 31, but she still felt comfortably established enough to take time off to have her children. "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, `OK, let`s slow this down a little bit`," she said. IANS
