Blac Chyna debuts baby bump

Rob Kardashian's fiancee Blac Chyna has debuted her baby bump after pulling out of two scheduled appearances due to morning sickness.

The model, who revealed she and Rob are expecting their first child on Friday (06May16), shared a photo on Snapchat.com, which revealed her burgeoning belly, along with her engagement ring.

The child will be Blac's second. She already has a three-year-old son, named King Cairo, with ex-fiance Tyga, who is currently dating Rob's youngest sister Kylie Jenner.

The baby bump picture emerged after Blac and Rob were forced to pull out of a club event in Los Angeles on Friday night, and another in Atlantic City, New Jersey on Saturday (07May16), due to the model's morning sickness.

They both shared the same image of the promotional poster for the New Jersey event on social media, and apologized to fans.

In a post that has now been deleted, Blac wrote on Instagram, "Sorry LA & Atlantic City I really wasn't feeling well LAST night which fell over to this MORNING causing us to miss our flight, Rob and I want to apologize for missing these events for we were looking forward to them as well but new dates are coming soon (sic)!"

The Kardashian-Jenner clan has yet to publicly congratulate the couple on its baby news, but Blac's mother, Tokyo Toni, shared her excitement over her daughter's pregnancy with a video posted to Instagram.

"I just got off the phone with my daughter and soon to be son-in-law and they told me I'm about to be a grandma," she smiled. "I'm super excited for them and I can't wait for this new addition to the family.

"As well, I'd like to congratulate the other side of the family, which are the Kardashians and the Jenners. Congratulations, guys. We're having a baby!"

Rob and Blac, real name Angela White, began dating in January (16).
