Jennifer Lawrence revealed that she did, in fact, know that Kylie Jenner was pregnant. The Hunger Games star knew about Kylie’s pregnancy, while the rest of us stayed in the dark.

The 27-year-old actress is a self-professed Kardashian superfan, and has hung out with the Kardashian and Jenner clan on several occasions. J Law has not only interviewed Kim Kardashian West on Jimmy Kimmel Live!, but the star also attended a dinner party at Kris Jenner’s house, and made an appearance at the family Christmas party.

Lawrence has also gotten quite drunk with momager Kris in the past, making it clear she is a good friend of the family, and has been keeping all of their secrets, particularly when she found out about Kylie’s pregnancy.

As most of us know, Kylie Jenner gave birth earlier this year to a baby girl, Stormi Webster, with boyfriend Travis Scott. The Keeping Up With The Kardashians star kept her pregnancy secret from the public before taking to her Twitter account to reveal she had given birth. Now that the Kylie Cosmetic creator is open about her pregnancy, stars are starting to reveal whether they knew of her secret pregnancy or not, including J Law!

Lawrence made an appearance earlier this week on Watch What Happens Live with Andy Cohen, and revealed she knew all along in a game of Plead the Fifth. When asked by host Andy Cohen if she knew Kylie was pregnant, Lawrence was quick to respond, “I did know Kylie was pregnant.” However, despite her closeness with the reality stars, Jennifer admitted she has yet to meet any of the Kardashian-Jenner clan’s children, including Kim’s newest family addition, Chicago West.

The hard-hitting questions didn’t stop there. Andy Cohen then asked J Law to rank the Kardashians from least to most favorite. The movie star compared it to Sophie’s Choice, but considering she had already "Pleaded the Fifth", she had to answer. J Law rated Kris and Kendall at the top of the list, all while leaving Kylie at the bottom. The star is currently on a press tour promoting her newest release, Red Sparrow, out now!
