The actress paired her glam look with a pair of diamond earrings, silver heels and her signature blonde locks out in waves.
Nicole's newest film, Boy Erased, follows Jared, the son of a small-town Baptist pastor who gets outed to his parents at age 19.
He's soon faced with an ultimatum - attend a gay conversion therapy program or be permanently exiled and shunned by his family, friends and faith.
Kidman plays Jared's mother, who comes to accept her son despite her husband's religious viewpoints.
Nicole stars alongside Lucas Hedges, Russell Crowe, and Joel Edgerton, premiering November 2.
