On Thursday, March 1, while appearing on Watch What Happens Live With Andy Cohen, the actress revealed to Cohen that she knew Kylie Jenner was having a baby.
"Um, I did know that Kylie was pregnant," Lawrence stated.
To some, it might be surprising that Lawrence knew Jenner was pregnant, considering that Jenner managed to keep her pregnancy a secret, so much that even her brother-in-law, Brody Jenner, didn't know she was expecting.
As previously reported, Kylie and her boyfriend Travis Scott kept mum to pregnancy news until on Feb. 4 when the cosmetics mogul took to Instagram to confirm it.
"My beautiful and healthy baby girl arrived February 1st and I just couldn't wait to share this blessing. I've never felt love and happiness like this I could burst!" the 20-year-old wrote.
Jenner also shared an 11-minute documentary-style video on YouTube titled "To Our Daughter," which followed her journey to motherhood.
J-Law Opens Up About The Kardashian-Jenner's
Since Lawrence was in on Kylie's secret, it would be normal to assume that she would've already met little Stormi Webster.. Surprisingly, she hasn't.
The Red Sparrow star further revealed that she hasn't met Kim Kardashian's daughter, Chicago West, either. However, this may not come as a surprise as Lawrence recently joked about her friendship with the KKW Beauty founder, calling it "one-sided."
"I don't know that she'd call me a friend," J-Law said in February at The Wing while promoting her new film.
Though the Oscar winner may be unsure of her friendship with Kardashian, she still has a lot of love for her and her family.
"They're nice people, [they're] very close. [They have a] loyal bond with one another, which I think is a positive thing to put into the world. They've been absolutely lovely to me" Lawrence explained.
Who is J-Law's Favorite Kardashian?
As per usual, Cohen is known for putting his guests on the spot. During a round of Plead the Fifth, Cohen asked Lawrence to rank her favorite Kardashian from the top favorite to the least.
Though she refused, she eventually revealed that Kendall is her favorite and then Khloe. Kim and Kourtney followed, which means Kylie and Rob are at the bottom.
Shortly after, Lawrence screamed that she would definitely place Kris Jenner at the top.
