As you may have heard, controversial Teen Mom 2 star Kailyn Lowry welcomed her third child, a boy (her third), on Saturday.
Not surprisingly, Kailyn's famous friends and her tens of thousands of fans were quick to offer their congrats on social media.
Yet one high-profile person in her life was surprisingly silent.
Lowry's former husband Javi Marroquin didn't react to news of the birth on social media, and in 2017, that's enough to make headlines.
At the very least, some fans wonder what he's thinking or not saying. To other obsessive Teen Mom 2 fanatics, it earns him condemnation.
Of course, that doesn't mean he's not acknowledging it at all.
Marroquin spoke about Lowry's big news in a new interview with Radar Online ... but Kailyn devotees probably won't like what he had to say.
“I’m glad everything went well for her,” Javi told the outlet.
That's nice obviously. But in reference to himself and his son with Kailyn, Lincoln, he added, “And we haven’t seen the baby yet.”
It's that second part that's got some fans in an uproar.
Even though it's been just two days since Kailyn welcomed her third child (we think ... Lowry has been uncharacteristically tight-lipped about the details), some fans are pissed that Javi hasn't brought her second son to see his brother.
Of course, that may have changed in the short time between when the interview took place and when it was published by the celebrity gossip site.
Don't tell that to the fans who are currently spewing venom in Javi's direction, though, and accusing him of being wrapped up in his new romance.
Some have blamed his absence on the fact that Marroquin is dating Lauren Comeau, but in all likelihood, he's just watching Lincoln for a couple days while Kailyn recovers.
Javi said prior to the birth that he'd been in contact with Kail about that, and planning for various scenarios regarding the birth and Lincoln's care.
As for the father of the still-unnamed baby?
Lowry revealed earlier in the pregnancy that she is no longer in a relationship with Chris Lopez, and she doesn't expect him to play any role in the kid's life.
That's just sad on every conceivable level.
We imagine becoming a single mother of three is a bit daunting, and Kailyn is probably happy to have a little time to bond with her new bundle of joy.
While her situation isn't conventional or without real hardships, at least her other two sons are with their dads, who care for them deeply.
In any event, it doesn't seem like Kailyn will have any trouble finding babysitters, as multiple co-stars have been quick to reach out.
Both Chelsea Houska and Leah Messer offered heartfelt congratulations on Twitter following the news of Lowry's birth.
Of course, Jenelle Evans has remained silent, so many fans have jumped to the conclusion that it's because of a past feud with Kailyn.
We may never know for sure.
And anyway, we're guessing Kailyn has enough on her plate these days without worrying what the Carolina Hurricane may be thinking.
In any case, watch Teen Mom 2 online tonight to relive the frequently rocky road that brought Kailyn to where she is today.
