Kidman's co-star Reese Witherspoon was also nominated for Best Actress in a Limited Series. Fellow star Alexander Skarsgard is up for Best Supporting Actor in a Limited Series, while Laura Dern and Shailene Woodley are both nominated for Best Supporting Actress in a Limited Series.
Kidman, who played Celeste Wright in Big Little Lies, said in a statement to Entertainment Tonight that she was "grateful" for the show's multiple nominations.
"We are all aware of how rare it is for a show and its cast to be honored in such a huge way, and we are all incredibly grateful," the actress said. "Thank you to the Hollywood Foreign Press [Association] for giving the show so much love."
"The character Celeste is precious to me and the recognition is deeply appreciated," she added.
