There's only one episode left in Season 2 of HBO's "Big Little Lies," and it's not one that fans will want to miss. Shailene Woodley and Laura Dern, who play Jane and Renata, respectively, both dropped some details about the award-winning show during their appearances on late-night television on Monday.

Woodley stopped by "Jimmy Kimmel Live!" and, after some light-hearted chat about her boyfriend and having a flip phone, revealed a major "cliffhanger" spoiler regarding the "Big Little Lies" season finale.

"In the beginning of the next episode... All of the women go to visit Perry's [Alexander Skarsgård] grave and his body's missing," she told host Jimmy Kimmel.

Woodley wasn't the only one who spilled secrets about the hit HBO show. Her co-star Dern revealed some off-screen tidbits about the cast when she appeared on "Late Night With Seth Meyers."

The conversation started when Meyers reminded the actress of a group chat she had with other members of the cast.

"Last time you were here you talked about the group text of everybody on the show," he said. "Is the group text still going strong?"

"It's going strong," she confirmed, making note that the group chat has since been named "The Monterey Five." Dern also admitted that her new castmate, Meryl Streep, wanted in on the chat.

“This other woman wants to like join the text,” she laughed. “Meryl. OK? We have our own group text."

Ultimately though, the nine-time Golden Globe winner made her way into the chat. “But then, of course, she writes the most genius thing ever, inspires us all to be better people," Dern explained. "And we’re like, ‘OK, you can be in our texts.'”

Catch the season finale of "Big Little Lies" this Sunday at 9 p.m. EST on HBO.
