Rob Kardashian and Blac Chyna is all over – again, for now. The reality star couple have split up once again, multiple sources have claimed in a new report.

The volatile couple, who met around this time last year and quickly became engaged, welcoming their daughter Dream Renee Kardashian in November 2016, have apparently gone off the rails again, with Rob reportedly finally coming to the end of his tether with his model fiancée doing disappearing acts and not communicating for extended periods of time.

“Rob thinks it's the right decision,” one source tells Us Weekly. “Chyna has disappeared for days at a time without communicating or providing any updates. This won't end well.”

A different source says that this particular trouble started around Christmas time, with 28 year old Chyna said to have taken their three month old daughter just before the holidays and disappeared, cleaning out the nursery and taking her belongings.

“[It's the same] with her yelling and screaming about how his family doesn’t like or support her, and his insecurities,” the second insider said.

The pair, who starred in their own E! series ‘Rob & Chyna’ last year, have for the meantime being living separately. Chyna moved back into her own home, while the 29 year old Arthur George designer has been staying at the Calabasas property his mother, Kris Jenner, bought this time last year.

Rob and Chyna, real name Angela Renee White, got engaged in April last year, having been dating for just two months. Weeks after that, she announced her pregnancy.

“His confidence was shattered for so long, so to have this banging girl all over him has given him a new lease on life,” a source said back then about how Chyna had turned his life round.

In among all the upheaval, the second series of ‘Rob & Chyna’ is apparently still going ahead.
