The reality star is really excited to be a father.
Rob Kardashian is so ready to be a father.
The 29-year-old reality star posted to Instagram on Thursday night what appears to be the same sonogram from earlier this summer, along with a very sweet message. "Can't wait for You," he wrote.
Meanwhile, in a promo clip for Sunday's episode of Rob and Chyna, we see that Blac Chyna's family is just as drama-filled as the Kardashians.

Chyna sits down for dinner with Rob, her father and stepsiblings, but things get pretty awkward when her mother, Tokyo Toni, shows up. "I'm really hoping that my mom is really nice at the dinner, 'cause she's known for, like, not giving two f**ks," the 28-year-old model voices her concerns. "I just hope she can keep her composure at the dinner."
Once seated, Tokyo completely ignores Chyna's father until she finds out that her daughter is the same age as her step sisters. "We're like triplets, special kind though," one of Chyna's siblings explains as Tokyo's mouth drops.
"So, it's true, huh. You're a rolling stone, Papa," Tokyo says to Chyna's dad. "That was an old life," he responds.

In June, Chyna spoke with ET about what kind of father she thought Rob would be to their baby. "Overprotective! For sure," she answered. "Loving, caring. Rob is just a big bundle of joy."
