Rob Kardashian and Blac Chyna are back together after what appeared to be their first vicious fight as a couple. The pair's first big argument came to light on July 25, Monday, when it was discovered that the 29-year-old reality TV star had deleted all traces of his pregnant fiancée from his Instagram account.

The couple, who is expecting their first child, was filming their upcoming reality TV show, "Rob & Chyna," over the weekend. During the shoot, they had a disagreement which soon led to an explosive fight between the couple.

Soon after, Kardashian took to Instagram and purged it from all the pics of his pregnant fiancée. The social media act triggered the rumors of breakup that spread like a wildfire with Twitterverse falsely reporting that the pair had unfollowed each other on Instagram.

"They were filming this weekend, and one of the people in her crew asked her to do something without him, and he snapped," an insider told Us Weekly. "They started talking again [on Sunday] though and made up [on Monday]."

Rumors were also rife that Kardashian has dumped Chyna after discovering suspicious messages on her mobile phone. Just days before the claim, Kardashian had duploaded a video of Snapchat in which he accused his pregnant partner of viciously scratching him. He calls her "psycho B***" in the video as she giggles and throws her hand towards him playfully.

However, the soon-to-be mother took to social media on July 25, Monday, to share a video in which she could still be seen wearing her massive diamond sparkler. The clip suggested that things are okay between the two after all.

"It's hard to see Rob and Chyna actually splitting," another source told People. "Rob is looking forward to becoming a dad. It would take a lot for him to break up with her."

Kardashian and Chyna made their relationship official in Feburary. Just three months later, the duo surprised their fans with the announcement of their engagement that was soon followed by the news of pregnancy. The child is due in October with reports that the duo is expecting a baby girl.
