When Rob Kardashian and Blac Chyna announced their engagement in April, the rest of the Kardashian Klan was eerily silent - even more so when the happy couple announced they were expecting shortly after. So we'd love to know what they think of this latest turn of events - E! has just announced they're producing a six-episode 'documentary' - ahem - dedicated to the pair.

With the working title Rob & Chyna, the reality TV show will "follow the whirlwind romance of Rob Kardashian and Blac Chyna," according to E!'s release, with a special episode devoted to the birth of the next Kardashian spawn. It's scheduled to premiere later this year, but in the meantime, you can read up on the sordid, incestuous history of the Kardashian-Tyga-Chyna-Kanye family here.
