Rob Kardashian and fiancée Blac Chyna revealed the sex of their unborn child in the series premiere of their brand new E! reality show Rob and Chyna.
Although we're kinda wondering if Rob is now regretting admitting before the big scan how much he wanted a son…
In the show, which aired last night in the US and premieres today on E! UK and hayu, Rob, 29, and Chyna, 28, are seen visiting their doctor for a scan and deciding to find out the gender.
Rob exclaims: "I'm pretty nervous. I'm excited I really want a boy!"
The doctor then announces it's a girl. Oops.
Rob and Chyna started dating in January and announced their engagement in April, followed by the news in May that a baby was on the way.
It was all very headline-worthy as the couple were so linked before they even got together: Chyna is close friends with Rob's sister Kim and has a son, King Cairo, with ex Tyga, who is dating Rob's younger sibling Kylie Jenner.
As you'd expect, the Kardashian family were quick to get on Twitter and share their excitement at another girl joining the family. This will be Kris Jenner's sixth grandchild: Kim has daughter North, three, and son Saint, nine months, while Kourtney Kardashian has sons Mason, six, and Reign, one, and daughter Penelope, four.
