Two of the best Australian actresses out there (although Cate Blanchett should always be mentioned in this category), Nicole Kidman and Naomi Watts, have been close friends for many years, often sharing stories of Hollywood success with each other - but it turns out that there was one kiss they owed big and small screens everywhere for the past three decades!

Last Tuesday night, Nicole Kidman and Naomi Watts attended the Women in Film's Crystal + Lucy Awards at the Hyatt Regency Century Plaza Hotel in Los Angeles, when Kidman revealed the "Mulholland Dr." actress and her owed each other a peck on the lips!

According to People Magazine, the context for Nicole Kidman and Naomi Watts' kiss was that the "Moulin Rouge!" Oscar winner took to the stage to speak about female empowerment, speaking about how, when she was 14, Jane Campion (who would go on to win an Oscar for "The Piano") approached her to star in a student film, and Kidman still regrets saying no three decades later.

Kidman's reason for saying "no" to the role? The script called for her to kiss a girl while wearing a shower cap, something she wasn't willing to do back when she was a teenager, but she has no problem doing now, as she showed while putting on a shower cap onstage while Watts did the same, and then sharing a Nicole Kidman and Naomi Watts kiss!

As Vanity Fair reports, the Nicole Kidman and Naomi Watts kiss is hardly the first one of its kind to make headlines; in the past, Madonna and Britney Spears locked lips onstage in an infamous embrace, and actresses Sandra Bullock and Scarlett Johansson did the same a while back.

According to Us Weekly, before entering the award show that saw Nicole Kidman and Naomi Watts together on stage, Tom Cruise's ex spoke candidly about her friendship with Watts, as they've been friends for nearly 30 years and claiming they were "like sisters."
