Rob Kardashian and Blac Chyna's baby's sex may have been revealed. According to Star magazine, the sock designer and the 28-year-old model are expecting a baby girl.

The magazine's source said that Rob wanted a son, but he would be happy too if he has a daughter. "Rob's ecstatic. Of course, he would have loved a boy, but he's grown up surrounded by women," the source told Star magazine. Meanwhile, Blac wants to have a baby girl, that's probably because she already has a son from her relationship with Tyga. "And Blac Chyna has always dreamed of having a daughter. They're having so much fun putting together the girliest of nurseries."

"Rob's a genuinely loving person. He is just a big bundle of joy...and has all the qualities of a good father. Rob's a big teddy bear. He'll be overprotective [of his daughter]. For sure," the source continued. It's not surprising that Rob has the qualities of a good father, because he has already proven it while interacting with Blac's three-year-old son, King Cairo.

Rob and Blac announced that they are expecting their first child in early May. The couple posted on their respective Instagram account an animated picture of Blac cradling her baby bump. Earlier this month, Blac opened up that Rob's very excited and couldn't wait for the baby. She's also sure that Rob could be a great father for their baby. "Rob has all the qualities of a good father... he'll be straight," Blac said.
