Nicole Kidman looks so different alongside 'bestie' Naomi Watts in unearthed photo

Nicole Kidman and Naomi Watts have an unbreakable friendship that goes back decades. Having met in the industry, the Australian actresses have gone to work together and support each other through thick and thin in both their professional and personal lives.

The Moulin Rouge actress, 57, and The Watcher star, 55, first crossed paths in the 1980s, but one photo of the two of them cosied up at a party in the mid-1990s shows Nicole looking almost unrecognizable.

The Oscar-winner polished off the look with ultra-glamorous long gloves, adding a touch of Hollywood sophistication.

The photo in question is the epitome of the 1990s. Nicole's strawberry blond curls were tumbling down over her shoulders as the star wore a chic black dress with spaghetti straps.

Nicole Kidman's gesture to BFF Naomi Watts about Liev Schreiber

Nicole is currently starring in Netflix's brand new thriller, The Perfect Couple , which also happens to star Noami's ex-partner, Liev Schreiber .

The two actors play married couple, Greer and Tag Winbury, who find themselves in hot water when a body is found on the grounds of their home where they are hosting a family wedding.

The pair were giving a joint interview with Entertainment Tonight in support of the show recently when they were asked what it was like working together, despite Liev being the ex of her close friend, particularly when it came to more intimate scenes.

Asking his co-star directly, Liev, said to Nicole on the red carpet: "I heard a story that you asked Naomi first if it was OK," to which Nicole replied: "Of course!"

Turning to the reporter, Liev then added: "Isn't that amazing? That's how close they are."

Naomi was also asked about her friend Nicole working with her ex and the conversation they'd had about the dynamic.

Speaking at the Toronto International Film Festival, Naomi said: "We always check in; we're besties. That was very kind of her to do that."

All is amicable between the trio as Naomi and Liev themselves seem to have a great relationship and look as if they co-parent their two children, Sasha and Kai, harmoniously .

Liev is now married to Taylor Niesen, while Naomi is married to actor Billy Crudup.

In 2016, shortly after they confirmed their split, Liev said on CBS This Morning: "Of course [the change is scary], but, you know, we're parents together so we'll be together for the rest of our lives no matter what and we're very close. Hopefully, that never changes, and I don't think it will."
