Rob Kardashian is counting down the days until he becomes a dad.
Robert Kardashian died of cancer at age 59 in 2003.
"Can't wait !! Miss you pops," he captioned a throwback photo of himself with his dad on Instagram.
Kardashian and Blac Chyna got engaged in April after three months of dating and announced the model's pregnancy the next month.
The reality star said in the Sept. 12 issue of People that he thinks his dad is "definitely happy, looking down.""I had a really close bond with my dad," he told the magazine.
"I was only with him for 15 years. That's why I'm looking forward to having that long-term bond with my child and being funny and goofy like my dad was."
The model is already mom to 3-year-old son King Cairo with her ex-fiance, Tyga, who is dating Kardashian's half-sister Kylie Jenner.
"He's a genuinely loving person and he's really supportive," she said at the time. "He's been supportive with me and even, like, the people that I'm around. I think he's going to do good."
"Pregnancy is treating me really, really good right now. I can't complain," the star added.
"[The best part is] just knowing that you have somebody that loves you unconditionally and you love them unconditionally."
Kardashian and Blac Chyna will give fans a glimpse into their relationship on the new E! series "Rob & Chyna."
