You are one shady sister, Khloé Kardashian! One smart fan accused the 33-year-old reality star of exposing Kylie Jenner's pregnancy way before the news came out. The Kardashian family released a Keeping Up With the Kardashians promo ahead of their 10-year anniversary special. In it, they recreated their iconic opening where Kris asks where Kim Kardashian is. Khloé (clearly annoyed) responds, "Mom she's always late!"

Sounds pretty standard, right? Wrong. We totally missed the fact that right when Khloé says "late" she looks at her pregnant little sister's baby bump. Whoa… how did we miss this sisterly side-eye?

Did you catch it? Honestly, we played it back a few times just to be sure. But, the fan is right. Khloé clearly looks at Ky when she utters the iconic line. And that's pretty bold of her considering she is pregnant with Tristan Thompson's baby.

And the Twitter user wasn't the only one to catch the sneaky reveal. One fan tweeted, "I noticed it right away." And another agreed that this clip proves that Kylie really is expecting (since she has yet to confirm the news herself). The fan tweeted, "Damn she really does look like she has a bump tho."

Knowing how candid Khloé is we're not surprised that she did this. Maybe it was just meant to be a little "wink" to her sister that no one would pick on — or maybe this was her way of telling the world: "Yes, she is pregnant."

Not all of the Kardashians have been so forthcoming though. Kim recently tweeted denying both of her sisters' pregnancies. "Let me just say this… People who supposedly work with us “confirming” details they know nothing about!" she tweeted earlier this week. "Especially when we havent even communicated with them SMH" So which is it? Are they confirming or denying? We can't wait until Khloé and Kylie set the record straight.
