Yes, that's right, the iconic Meryl Streep will join Nicole Kidman, Reese Witherspoon, Laura Dern, Shailene Woodley and Zoe Kravitz in their incredible squad for the show's second season.
Streep, who just bet her own Oscars record, is set to play Mary Louise Wright - the mother of Kidman's on-screen husband Perry Wright (Alexander Skarsgard).
Kidman and Witherspoon are both definitely returning to star in and produce the Emmy award-winning show, with negotiations currently underway to secure season 1's other stars, such as Shailene Woodley, Zoe Kravitz, and Laura Dern.
Liane Moriarty, who wrote the original novel Big Little Lies, is also involved with the second season, which is partially based on a story by the Australian author.
HBO said in a statement that season 2 would explore the "malignancy of lies, the durability of friendships, the fragility of marriage and, of course, the vicious ferocity of sound parenting. Relationships will fray, loyalties will erode … the potential for emotional and bodily injury shall loom."
