Kim Kardashian, Kylie and Tyga respond to Rob and Blac Chyna’s baby bombshell

They might not have responded to their engagement news, but it looks like Rob Kardashian’s family are willing to publicly congratulate him and fiancee Blac Chyna on their pregnancy news.

Rob and the model announced they were expecting their first child together in identical Instagram posts shared on Friday.

While things initially remained quiet, within a few hours their nearest and dearest steadily began to comment.

First up was Blac’s ex fiance and baby daddy Tyga – who is also the boyfriend of Rob’s younger sister Kylie Jenner.

“Congratulations,” the rapper wrote under Blac’s picture along with a number of streamer emojis.

Then Kim Kardashian, who is currently holiday in Cuba with Kanye, Kourtney, Khloe and the kids, liked Rob’s picture.

Blac’s former nemesis Kylie, 18, soon followed suit.

Blac, who is also mum to three-year-old King Cairo, is reportedly several months along.

Despite making no secret of the fact having a baby was one of their top priorities soon after they confirmed their blossoming romance, the announcement still came as a massive shock to most of their fans – an no doubt the Kardashian clan too.
