It looks like Rob Kardashian and Blac Chyna's falling out has only brought the pregnant model and her former frenemy Kim Kardashian closer together!

In a Snapchat video posted Tuesday, the reality star checked in with fans from her grandma MJ's birthday party in San Diego, turning the camera on Chyna and giving her baby bump a little rub.

As Life & Style previously reported, Rob unfollowed his fiancée on Instagram earlier this week while simultaneously deleting all of his photos.

And a source tells In Touch that the couple has officially called it quits after Rob found racy text messages sent to her ex Tyga.

"Rob lost it," the source shares. “He was yelling, ‘People told me to watch out for you!’ and ‘I hate cheaters!’”
