Streep will play the mother of Perry Wright (Alexander Skarsgård), abusive husband to Celeste (Kidman). His character was (Season 1 spoiler alert!) killed in the first season.

According to The Hollywood Reporter, Streep's Mary Louise is concerned for her grandchildren in the wake of his death, and she's arrived in Monterey in search of answers.

As The Playlist pointed out on Twitter, Streep and Skarsgård already have an onscreen connection ... sort of.

We're guessing this isn't actuallycanon, but we don't care, we're going to assume it is and no one can tell us not to.

Alexander Skarsgård is expected to return for the second season of Big Little Lies. No other cast members are locked in at this time – though it seems a safe bet Zoë Kravitz will be back, seeing as the second season is expected to introduce Bonnie's parents.

Big Little LiesSeason 2 will run seven episodes. Series creator David E. Kelley has written all seven episodes, just as he did for the last season. Liane Moriarty, who penned the novel that the first season was based on, helped craft the story.

Andrea Arnold is directing the entire season. She replaces Jean-Marc Vallée, who helmed the last season.

There's no word yet on when Big Little LiesSeason 2 will air – but you can bet we'll be parked in front of our TVs watching when it does, especially now that they've gone and gotten Streep in the mix.
