Ever since Blac Chyna announced her pregnancy to the world, she"s been diligent about keeping us apprised of the status of her baby bump.
The world is intrigued, possibly because it holds the progeny of Rob Kardashian and will carry on the K name.
But another young "un who is duly fascinated with Chyna"s bump, but for a very different reason, is her three-year-old son King Cairo.
In a new Instagram post, the model shares a video featuring King rubbing his mom"s growing belly.
"Awww," Chyna says as the tot approaches his mother while she"s lying down and gently strokes what will be his new baby brother or sister.
While Chyna has appeared in many a curve-hugging dress showing off her pregnant belly, this is only the second time she"s revealed it in an unclothed state.
The first time we saw the naked bump was about a month ago, just around four weeks after she and Rob announced they were expecting.
In it, we can see for the first time that she"s really "popped."
Later that month, Chyna shared a video of herself stepping on the scale to track her weight.
We can hear King playing in the background as she exclaims, "Uh-oh. Mommy gained 20 pounds!"
Then in a second video, King asks about the sex of the baby.
"Is it a boy or a girl?" he asks.
"I don"t know, what do you want it to be?" Chyna responds.
"Am I squishing the baby?" he asks later as he lies on his mother"s stomach.
We"re not sure how Blac and Rob will one day explain to King the convoluted family dynamics this little baby will create, but we suppose that"s a conversation for another day.
