Blac Chyna's Instagram hack leads to the leak of incriminating messages about the Kardashians.

Reality TV star Blac Chyna‘s Instagram was hacked yesterday and a series of strange images were posted on her account.

The hacking followed Rob Kardashian’s announcement on his own Instagram page that Chyna, 28, had taken their baby girl Dream and left him.

In one post, the unnamed person who gained access to Chyna’s account announced this was true. Other screen shots also suggested that she was leaving her fiancé and father of her second child, Rob.

“Just to let you all know that’s not me on my IG page,” Chyna explained to followers in a video. ‘That’s somebody that hacked me and somebody’s really, really, really, really, really mad.”

The hacker also shared screenshots of conversations that appeared to be between Blac Chyna and the rappers Jayden Smith and Young Thug. The conversations suggested that she planned to meet up with the men.

The hacker then shared a post that claimed they had proof that Blac Chyna had a plan to trademark the name Kardashian as soon as she was married to Robert.

In one long conversation, Chyna also appears to tell her best friend Treasure of her plans to give Rob a year to get into shape or she will leave him.

“He’s lazy, fat, insecure,” the 28-year-old wrote. “Imma give rob 1 year to get it together or I’m gone.”

Her friend tells her to “just stack ur money” and that “Kris will make sure y’all stable always.”

The conversation then turned to getting Rob “in line”, with Chyna reportedly writing, “I don’t wanna treat him like Tyga but I will. Imma slap the s*** outta him.”

Earlier this month, Chyna was allegedly blocked from changing her name to “Angela Renee Kardashian” by her partner’s famous siblings, Kim, Khloe and Kourtney on the grounds the family’s brand would “suffer damage including irreparable injury to their reputation and goodwill,” according to celebrity news site TMZ.

Chyna eventually regained control of her account, deleted the hacker's posts and posted an image advertising her upcoming reality TV special, which featured her older son King holding the newborn. This image has now also been deleted.
