Get excited, Big Little Lies fans!

On Thursday, Nicole Kidman Instagrammed the first on-set shot of Meryl Streep from Big Little Lies season two. Kidman shared a photo of the two cuddling with her twin sons on the show -- Josh and Max, played by Cameron and Nicholas Crovetti -- while looking at an iPad.

"First day on the set with Meryl and 'my' darling boys! #BigLittleLies," Kidman wrote.

Streep will play Mary Louise Wright, the mother of the recently deceased Perry Wright (Alexander Skarsgard). Perry -- the abusive husband of Celeste (Kidman) -- died at the end of season one at the hands of Bonnie (Zoe Kravitz). According to a statement by HBO, Mary Louise is described as a woman who arrives in Monterey searching for answers and is concerned for the well-being of her grandchildren following her son's death. 

ET was the first to break the news of the new character.

ET spoke with Kidman and fellow BLL star Laura Dern at the Calvin Klein Fall 2018 runway show in February, when they both gushed about Streep's addition to the already star-studded cast, which includes Reese Witherspoon. 

"Reese and I were just [thinking], 'She would be so amazing in the role!'" Kidman recalled, admitting that at first they didn't think they could nab her.

She also shared that the role was specifically written for the three-time Oscar winner.

"It was written for her and we wanted her," Kidman noted.

"It's amazing!" Dern echoed. "When I tell anyone in my life that Meryl Streep is joining us, it's incredible!"

Meanwhile, on Wednesday, Robert De Niro told ET that he would definitely be up for playing Streep's husband on the HBO hit!

"Television is not the way it was when I was a young actor," De Niro noted when ET spoke with him in New York City at an event promoting the Tribeca Film Festival. "It's totally different. They’re doing very good work in television."
