While they have been dating just five months, Chyna has publicly said she wants to have Kardashian’s baby as soon as possible.

The couple both took to Instagram to post an emoji indicating they had a baby on the way.

TMZ reports that Chyna, real name Angela White, is several months along.

While it will be the 29-year-old Kardashian’s first child, Chyna has a three-year-old son named King Cairo with former fiance Tyga, who is dating Kardashian’s younger half-sister, Kylie Jenner.

Tyga sent his well wishes, writing “Congratulations” under Chyna’s announcement.

Chyna, whose best friend is Amber Rose, the former girlfriend of Kim Kardashian’s husband Kanye West, has been in a long-running feud with Rob’s family.

Khloe Kardashian, who has been her brother’s biggest supporter as he fought depression and put on a lot of weight, kicked him out of her house after she discovered he was dating Chyna.

Some of the family have been mending fences with Chyna. Kylie Jenner recently posted a picture of her and Chyna together.

Chyna’s mother Tokyo Toni said in a recent interview that she expected her daughter to get pregnant right after marrying Rob.

“I want another grandchild, for sure. It’s very likely to happen after the wedding,” the 45-year-old said, adding that the Kardashians will have to put aside any ill feelings when Chyna has Rob’s baby.

“At the end of the day, they’re all not going to have a choice if children come into play,” Tokyo, real name Shalana Hunter said. “At that point, Kris and I will be that child’s grandmother.”
