HBO's Big Little Lies just got stacked with another Oscar-winning heavyweight.

Meryl Streep will join David E. Kelley's hit Emmy- and Golden Globe-winning TV drama series, based on the 2014 Liane Moriarty novel, for Season 2. Streep will feature alongside fellow Academy Award-winning stars Reese Witherspoon and Nicole Kidman, who have already signed on for the second installment.

According to The Hollywood Reporter, Streep will portray Mary Louise Wright, the mother to Celeste Wright's (Nicole Kidman) abusive husband, Perry Wright (Alexander Skarsgard).

Described as "a woman who is concerned for the well-being of her grandchildren following her son Perry's death," Mary arrives "searching for answers" from her daughter-in-law.

THS reports that Big Little Lies, which took home a whopping eight Emmys and four Golden Globes, will see Kelley return as show writer. HBO says the series will continue to explore "malignancy of lies, the durability of friendships, the fragility of marriage and, of course, the vicious ferocity of sound parenting" — simply put: drama abounds!

Big Little Lies' second season is greenlit for seven episodes. HBO announced the series would receive another installment on December 8, 2017.
