Los Angeles: Model Blac Chyna and reality TV personality Rob Kardashian say they plan to expand their family after their first child is born. "Rob wants me to have like four more, or something like that. Three more, so four total. Plus King (Cairo), that's five," Chyna spoke on Facebook live video, reports femalefirst.co.uk. The “Keeping Up With The Kardashians” star backed his request by praising his mother Kris Jenner for having five children and still look amazing. He said: "That's what my mom did. She did five and she pushed them all out. Look at my mom! My mom is banging!" "Your mom looks bomb, though," Chyna added. The engaged couple is set to get their own reality TV show called "Rob and Chyna" which will premiere shortly.
