DING! DING! DING!
It is apparently on once again between Rob Kardashian and at least one of his siblings.
The often-troubled reality star has feuded numerous times in the past with his family, most notable leaving Kim Kardashian's wedding weekend early back in May of 2014 after getting into an argument with the bride-to-be over his weight.
Rob didn't even see his sister get married to Kanye West as a result of that fight.
So, what has set Rob off this time around? And how did he react to the disagreement?
Based on his own mini Twitter rant, it appears as if Kylie Jenner and maybe a few other relatives recently threw Rob a baby shower.
Except there was one problem: they did not invite Blac Chyna, Rob's fiancee and the woman actually having his baby.
In response to this alleged snub, Rob did not merely call Kylie out on social media.
He released her phone number to the world!
"Kylie's # ... I ain't hacked either this is rob dog lol," Kardashian seemingly wrote on Monday night, along with the phone number and 16 crying-laughing emojis.
His same official account then followed this initial tweet with a second post that only listed the number of the youngest Keeping Up with the Kardashians star.
You know, in case anyone missed it the first time around.
The number is now out of service, but an insider tells People Magazine that it really did belong to Kylie.
Shortly after revealing this private information, a third tweet (posted by Rob, we assume again) made it pretty clear why Kardashian was so bitter.
"Didn't invite the Mother of my child to a baby shower you all were trying to throw for me ‼? You all must have lost your damn minds," it reads.
It certainly would seem rude to throw a baby shower and not invite the person actually giving birth to said baby.
But is there any real doubt that those who watch Rob & Chyna online will simply see this feud and this storyline play out on some future episode?
Can anything be truly believed when it comes to this family and their supposed beefs?
Or is everything scripted by producers for an eventual reality show payoff?
The Rob & Chyna actor, who is expecting a girl this fall, has publicly reacted on social media in the past.
In July, Rob purged his Instagram account of all references of his relationship with Blac Chyna after the two had a fight.
Prior to that, he had taken a nearly two-year hiatus from all social media as a result of his aforementioned fight with Kim Kardashian.
Still. It's one thing to erase things from your own account. That's harmless.
It's another think to actually unveil private information such a as phone number to millions and millions of people.
Did Rob cross a line in this instance?
Did Kylie deserve if if she really organized a baby shower and did not extend an invitation to Blac Chyna?
Are we already spending way too much time thinking about this fight and analyzing it from all sides?
We are, aren't we?
Fair enough. Let's take a look back at how Rob's sisters reacted to the news that Blac Chyna is marrying their brother:
