The Kardashian Klan is reportedly about to gain another queen — well, a princess in this case. According to Us Weekly, Rob Kardashian and Blac Chyna are expecting a baby girl!

A "source close to the pair" reveals that the reality TV couple, whose first child together is due in October, are "preparing for their daughter's arrival" by designing an "over-the-top extravagant" nursery in the lone male Kardashian's home in Calabasas, California.

The tabloid also reports that Kardashian momager and matriarch Kris Jenner has become closer with her once semi-estranged son since news of his fiancee's pregnancy was announced.

"Kris has been giving him baby advice," the source claimed.

Apparently, Jenner has also bonded further with her future daughter-in-law, Blac Chyna. A family source adds, "They get excited talking about the baby!"

And while the pregnancy is a first for Kardashian, Blac Chyna is already a seasoned mom: The model and emoji/false lash hawker shares a son, King Cairo, with her ex, rapper Tyga — the on-again, off-again beau of Rob Kardashian's half-sister Kylie Jenner.

The happy couple, who announced their pregnancy on May 6, is also set to star in their own Keeping Up With the Kardashians spinoff show, a six part docu-series called Rob & Chyna, due out later this year. It's likely their precious first baby memories will be chronicled on the show.
