Hollywood power couple Nicole Kidman and Keith Urban recently celebrated their 18th wedding anniversary, with Kidman and their daughter Sunday Rose stealing the show at Paris Fashion Week. The duo turned heads with their coordinating looks at Balenciaga's Haute Couture fall/winter show. Kidman sported a chic short-sleeved dress with a mermaid skirt, while Sunday mimicked her mother's style in a matching outfit. The mother-daughter pair wasn't the only one making waves at the event, as they were joined by other celebrity duos including Naomi Watts and her daughter Kai, as well as Maya Rudolph and her daughter Pearl. Kidman, who also shares two other children with ex-husband Tom Cruise, has continued to captivate audiences with her timeless style and undeniable star power.
