Kourtney Kardashian has praised sisters Kylie Jenner and Khloe for being the "fun" aunts, but - there's not much fun when both Khloe and Kourt and even Kendall have failed to acknowledge their brother Rob's baby news.
The 37-year-old Keeping Up With The Kardashians star, who has children Mason, six, Penelope, three, and 16-month-old Reign with her ex-partner Scott Disick, his vocal on her social media pages but has made no reference to Rob and Blac Chyna'spregnancy news .
Neither has Rob's mum Kris Jenner. While Kim Kardashian and Kylie who have acknowledged the news on social media.
Instead the Kardashian-Jenner clan have been gushing over their Cuba trip as they return back to Los Angeles.
Kourtney recently spoke to the website The New Potato about how her family get along with her kids, and whether they give advice to her brood, the brunette beauty said: "I feel like Khloé is definitely the fun, playful aunt, and Kylie has about a million pets, so they love to go play with her pets.
"It's nice to see the way they interact with each other and how they all bring different things into their lives with their different personalities.
"But I don't really see them giving them advice ... yet."
We're sure that Rob's baby when it arrives will be welcomed with open arms in this rapidly expanding family.
Rob and the model announced they were expecting their first child together in identical Instagram posts shared on Friday.
While things initially remained quiet, within a few hours their nearest and dearest steadily began to comment.
First up was Blac’s ex fiance and baby daddy Tyga - who is also the boyfriend of Rob’s younger sister Kylie Jenner.
“Congratulations,” the rapper wrote under Blac’s picture along with a number of streamer emojis.
Then Kim Kardashian , who is currently holiday in Cuba with Kanye, Kourtney, Khloe and the kids, liked Rob's picture.
Blac's former nemesis Kylie, 18, soon followed suit.
Blac, who is also mum to three-year-old King Cairo, is reportedly several months along.
Despite making no secret of the fact having a baby was one of their top priorities soon after they confirmed their blossoming romance, the announcement still came as a massive shock to most of their fans - an no doubt the Kardashian clan too.
The couple became engaged in March just three months after they began dating, and this could well be the reason behind it.
Meanwhile, someone from Blac Chyna's camp has claimed the baby news was leaked by a Kardashian family member after it made its way onto a celebrity website on Friday.
The pair had been planning to announce it on Sunday - Mother’s Day.
They told People magazine: "She would have preferred to have announced it on Mother's Day herself, but her hand was forced.”
"Allegedly the other half of her family leaked her story so she had to announce it.”
The spokesperson added that the only people who knew about the news was himself and Blac’s good friend Amber Rose, and said they could have done it to promote their show.
"The only people that knew from Chyna's side was myself and Amber. Her mother didn't even know. [Chyna's] moment was taken from her, which is really sad.”
The news comes just weeks after Kim reportedly played peacemaker between Kylie and Blac.
The 35-year-old reality star intervened to call a truce between Blac and her 18-year-old sister in order to ease tensions after Rob popped the question.
Speaking to TMZ about Kim's interference, a source close to Blac claimed she received a phone call from the Keeping Up With the Kardashians TV personality asking her to resolve the dispute over both matters, prompting her to visit the brunette star's home to discuss the matter.
Apparently putting their differences aside, the pair then posted a string of pictures to their social media accounts.
Kylie even captioned one: "When we've been best friends the whole time."
