Nicole Kidman used her Emmy Awards acceptance speech on Sunday night to speak out against domestic violence.

Kidman won best actress in a limited series for her role on HBO’s Big Little Lies, playing a character who is physically abused by her husband.

“We’ve shown a light on domestic abuse,” Kidman said as the crowd applauded. “It is a complicated, insidious disease. It exists far more than we allow ourselves to know. It is filled with shame and secrecy. And by you acknowledging me with this award, it shines a light on it even more. So thank you, thank you, thank you. I bow down to you.”

Kidman was one of a number of Big Little Lies winners on Sunday, joining Laura Dern (supporting actress), Alexander Skarsgard (supporting actor), and director Jean-Marc Vallée.

The actress, an Oscar winner, thanked them all — and gave a special shoutout to costar and producer Reese Witherspoon, whom she defeated in the category on Sunday.

“Reese, I share this with you. Without you, I would not be standing up here, so…” Kidman said.

The drama was created and written by David E. Kelley and based on the novel by Liane Moriarty. Set in the affluent Californian city of Monterey, the residents are shaken by the occurrence of a murder during the local school’s themed trivia night. Neither the victim nor the culprit is revealed until the final episode of the series, which was nominated for a whopping 16 Emmy awards overall.

Kidman beat out fierce competition from Witherspoon, as well as Jessica Lange and Susan Sarandon both for Feud: Bette and Joan, Carrie Coon in Fargo, and Felicity Huffman in American Crime.
