The King Kong star met the actress when they worked together in 1991 movie Flirting, and she admits Kidman helped her as a struggling actress trying to get ahead in Hollywood.

Watts tells U.S. OK! magazine, "I was lucky that Nicole Kidman was always there to support me, console me, keep my spirits up and help me believe in myself. She's been such a good friend over the years. It was scary trying to find work and having no money and no medical insurance.

"I had very few friends and would spend days alone, sitting in cafes feeling miserable. Even when I started becoming famous I never forgot what it felt like to worry about making ends meet."
