Is Blac Chyna Pregnant? Rob Kardashian Posts Cryptic Instagram Photo

Blac Chyna turned heads Monday when she posted a photo on Instagram with what appeared to be Rob Kardshian’s arm wrapped around her. Now, the 28-year-old “Keeping Up With the Kardashians” star is using social media to fuel rumors that he’s dating the 27-year-old model.

On Tuesday afternoon Rob posted a photo of Blac Chyna carrying a baby car seat. The picture appears to have been taken by paparazzi, but someone added text to the top of it.

“Blac Chyna probably out shopping rite now as she plan to give birth to the only next generation of the Kardashian Name! #BabyKardashian,” the text reads.

It’s not clear if Rob added the text to the top of the photo, but he did insert five shamrock emojis in the caption. The shamrock emoji is a reference to Blac Chyna’s Instagram post from yesterday. She captioned the picture “The beginning” and added the emoji to the end of it.

Although Rob’s post certainly fuels rumors that the two are dating – or maybe even expecting a child together – they have yet to officially confirm that they are in a relationship. In fact, many fans seem to think that Rob is "trolling" his family due to their previous spats with Blac Chyna.

For those who haven't been following the latest Kardashian drama, Blac Chyna is the ex-fiancée of Kylie Jenner's boyfriend, Tyga. The two also share one child together, King Cairo, 2. Their breakup was an ugly one, with Blac Chyna using social media to take shots at her ex and Kylie, who was only 17 when they started dating.

Although Blac Chyna has not been in any recent fights with the Kardashian family, Kylie is allegedly very upset that her half-brother is getting involved with the model. A source told People magazine that the now 18-year-old is "livid."

"She feels super betrayed and can't understand why someone in her own family would stab her in the back like that," the insider explained.

Meanwhile, TMZ is reporting that Blac Chyna and Rob's relationship is simply "playful." Blac Chyna reportedly introduced Rob to her personal trainer, and the pair have been working out together.
