Rob Kardashian and Blac Chyna's baby may be expected soon.

HollywoodLife.com reported that Blac Chyna's mother, Ms. Tokyo Toni, has revealed that she wants another grandchild. She also shared her thoughts on when it might be.

"I want another grandchild for sure," Blac Chyna's mother told NW magazine. "It's very likely to happen after the wedding."

"Rob is the perfect dad. He spends hours playing with King and he buys him lots of toys. Their favorite thing is playing a numbers game with Legos. King responds to him so well."

There are speculations that the controversial couple is planning to get married in the summer. Can fans expect Rob Kardashian and Blac Chyna's baby by then as well?

"I didn't expect it and I know my daughter wasn't expecting it," Chyna's mom said about the engagement.

"They spend every hour together during the day so they're already like a married couple," Toni added. "They do have arguments but he concedes to her every time. He just goes, 'OK babe!' Even their arguments are short and cute."

Meanwhile, the Kardashian-Jenner clan is believed to be livid over the engagement. "The family is really not into the engagement," a source told People.

"Khloé and Kylie think Chyna is desperate, thirsty and playing with Rob's head. They're also concerned she is after his money and that she is dying to stay relevant and get back at Kylie by being with Rob."

"As far as they're concerned," the insider added, "Blac Chyna will never be a Kardashian."

It was previously reported that Rob Kardashian and Blac Chyna may earn $1 million for the TV special of their wedding. The "Keeping Up with the Kardashians" star is said to be gearing up for a "triumphant return to the spotlight" in a TV special with his lady love.

This comes after the reclusive actor has shied away from the public eye for about two years.
