Naturally, her first post was as awesome as one would expect from the 50-year-old actress. "About last night......shut the place down!!!" she captioned a photo of herself inside The Beverly Hilton in Los Angeles. "I am so proud of my Big Little Lies family and to have stood with my sisters on such a special night. #TimesUp."
Kidman took home the award for Best Actress, Limited Series or TV Movie, beating out her co-star, Reese Witherspoon. The HBO series also won for Best Limited Series or TV Movie, with Alexander Skarsgard and Laura Dern securing additional wins in the Best Supporting Actor and Actress categories.
