Naomi Watts and Nicole Kidman

Actresses Naomi Watts and Nicole Kidman went to high school together and were also part of the same theater company in Australia. But it was in 1991, during the filming of Flirting, that they became best buds.
The relationship has stood the test of time. In 2007, they went to the Oscars as each other’s dates. They remain best buds to this day.
