Unfortunately for Kendall Jenner, James Corden keeps up with the Kardashians.
Jenner joined Corden's show on Wednesday for a game of "Spill Your Guts or Fill Your Guts," which is like truth or dare if every dare was eating something disgusting. The reality star was a good sport, ranking her nieces' and nephews' names from best to worst and drinking bird saliva instead of saying which member of the Taylor Swift squad was her least favorite.
I don't know about you, but that's what the squad do.
Then came the big question ...
While Kendall was faced with the prospect of either answering a question or drinking clam juice, Corden said, "Your sister Kylie was supposed to be on our show tonight, but she canceled yesterday morning because she was sick. Yeah, she was sick."
"Here's a paparazzi photo of her," said the host, showing a very recent picture of Kylie walking around.
From their reactions, Kris and Kendall Jenner probably weren't expecting that.
"My question is, 'How's she feeling?'" said Corden.
"Drink the clam juice!" Kris yelled.
Kendall did end up drinking the clam juice, so we'll never know for sure how Kylie is feeling, but we're going to guess she's doing a little better than her sister:
"The Late Late Show with James Corden" airs weeknights at 12:37 a.m. ET on CBS.
