As you've probably heard, Kim Kardashian welcomed a son over the weekend, and predictably, her fans went wild.
Kim's social media pages have been exploding with well-wishes and nosy demands for details, but one member of the reality star's inner circle has made no mention of Kim or the baby and seems as though she couldn't care less about her new nephew.
Yes, Kylie Jenner hasn't so much as tweeted her congrats to her older sister.
In fact, the 18-year-old Instagram queen probably hasn't even met the kid, as she's currently in Miami for the Art Basel show.
Kylie even passed up an opportunity to give a shout-out to Kim and Lil Yeezy Jr. when she snubbed a bunch of paparazzi who questioned her about the new bundle of joy.
But that doesn't mean Kylie has been quiet on social media.
No, she's clearly enjoying her time in Miami, posting her usual round of selfies and group pics with her stylish friends.
Of course, it's not all fun and games. Kylie's lip kits are very much on her mind, and she's clearly very concerned about how her fans will react once they receive their overpriced makeup in the mail.
"Let this weekend be over so everyone can get their lip kits," Kylie tweeted last night.
Her seeming indifference to the fact that her sister just gave birth after an extremely difficult pregnancy has led many to wonder if Kylie is jealous of all the attention being heaped upon Kim and her new baby.
There have always been rumors about Kylie and Kim feeling competitive toward one another, but the relationship between the sisters may have recently reached full-blown cold war status.
Kim reportedly sees Kylie as the only real threat to her position as most popular Kardashian-Jenner sister, and sources say Kylie is intent on snatching the crown.
We're sure she's very happy about the latest addition to the ever-growing Kard clan, but we can definitely see a part of Kylie's brain immediately switching over to PR mode and strategizing about how to shift some of the attention back to herself and the crap she sells to her fans.
