This isn't good...

Rob Kardashian unfollowed Blac Chyna and deleted all photos of her from his Instagram account over the weekend, and the sock designer allegedly dumped his pregnant fiancee after discovering suspicious messages on her phone, the Mirror reports. The worst part? It all went down while they were filming Keeping Up with the Kardashians, according to Media Take Out. It's probably the only unscripted thing that's ever happened on the reality show!

This isn't the first time Kimmy K's little bro has prompted split rumors on social media. He pulled the same move back in March, but explained it away by claiming the couple just wanted more privacy.

"Chy and I are not broken up we just feel like it would be a lot healthier for our relationship if we kept a lot more to ourselves. It's impossible to have a positive relationship with so much negativity from the media and outsiders and we would appreciate it if everyone respects that," he wrote at the time.

The former stripper seems to be hanging on by a string, and is still following her man as of now. This is what the whole Kardashian clan warned him about!
