Mini Chyna, is that you?

After revealing the sex of her and Rob Kardashian‘s little one on their highly-anticipated reality show, Rob & Chyna, bride-to-be Blac Chyna showed off her baby bump Sunday night at a Hollywood bash in celebration of the premiere.

The reality star, 28, took to PH Day Club in a form-fitting, mesh ankle-length dress with a nude bodysuit underneath — and her baby bump on full display.

Chyna and Kardashian, 29, announced that they are bringing home a baby girl.

The engaged couple weren’t the only ones excited about the news.

Kim Kardashian West gushed about the revelation in a Twitter post, writing, “A girl!!!!!!!!!! how cute is she going to be!!!!!!!”

Kardashian and Chyna have long kept mum about whether they were having a little boy or girl. The couple previously opened up to PEOPLE about how excited they are to build a family together.

“We definitely discussed having kids,” Chyna said last month. “Rob made it very clear that he wanted to have a baby. Babies, actually! He wants me to have, like, four.”
