Blac Chyna's dad claims she and Rob Kardashian are expecting a son

Blac Chyna's father claims she and Rob Kardashian are expecting a little boy together.

The 28-year-old model is currently pregnant with her second child, but first with her reality star fiance Rob. Blac already has son King Cairo, three, with ex Tyga, who is now dating Rob's half-sister Kylie Jenner, and according to her dad Eric Holland she'll be welcoming another son soon.

He says his daughter, real name is Renee Angela White, and Rob, 29, told him the gender of their unborn tot on Independence Day (04Jul16).

"Rob and I have had some one-on-one time. All I can say is he's excited about the prospect of a boy," Eric told Britain's Now magazine. "For Angie, the most important thing is that the baby's healthy. They were really excited when it kicked for the first time.

"They've chosen the name but not told anyone what is it. They want to wait until the baby is born."

Blac and Rob have been dating since January (16) and announced their engagement in April. Eric says the couple is "great" together and he predicts they won't stop at just one child.

"I said to Rob: 'I know you're just going to keep going with Angie until you get more than one boy, right?' and he laughed," Eric added. "It wouldn't surprise me if they went on to have four or more kids."

He also dismissed rumors that his daughter is using Rob - whose siblings are Kourtney, Kim and Khloe Kardashian, along with half sisters Kendall and Kylie Jenner - as a "stepping stone", and insists they love each other very much.

Eric briefly touched upon the pair's wedding plans too, hinting a ceremony could be taking place in early 2017, though they haven't set a date yet. He can't wait to have Rob as a son-in-law, praising the sock designer for being down to earth and not flaunting his fame.
