The reclusive Kardashian -- who currently has just two Instagram posts on his verified account -- posted a meme on Tuesday featuring a makeup-free Blac Chyna carrying a car seat. The picture reads, "Blac Chyna probably out shopping rite now as she plan to give birth to the only next generation of the Kardashian Name! #Baby Kardashian."
Rob captioned the pic with four-leaf clover emojis, presumably calling himself a lucky guy.
A source close to 28-year-old Rob confirmed to ET on Tuesday that Rob and Blac Chyna are currently dating, and are in fact a real couple.
The new romance is presumably causing drama within the Kardashian clan, given 27-year-old Blac Chyna's history with the family. The "Rack City" music video star used to be close friends with Kim Kardashian, but the friendship cooled after Kim's 18-year-old sister, Kylie Jenner, started dating 26-year-old rapper Tyga. Tyga is Blac Chyna's ex-fiance, and the two have a 3-year-old son together, King Cairo.
