Blac Chyna tweeted her fiancé Rob Kardashian's phone number on Sept. 29, Thursday, causing a Twitter meltdown. This happened just days after Kardashian revealed his half-sister Kylie Jenner's phone number on social media.

It has been confirmed that the number really belonged to Kardashian. However, the number was disconnected shortly after Chyna posted the tweet.

The "Rob & Chyna" stars' relationship seems to have hit a rough patch with several reports claiming that the couple are heading for splitsville. However, an insider told E! News that even though the couple are living separately, they working on their relationship. 

"Rob and Chyna are fine," the source revealed. "They are together, but it's just difficult right now." 

The source explained that Kardashian and Chyna are living separately because it makes life more harmonious for both of them. Although they often argue, they love one another, the source added.

Another source told People that the two are not in a great place and they have not been speaking recently. While the two, who are expecting their first child together, are not broken up, their relationship is not healthy at all, according to the source. 

Kardashian and Chyna's relationship is a controversial one as Jenner is the current girlfriend of Tyga, Chyna's former boyfriend. Tyga and Chyna has a three-year-old son named King Cairo.

Kardashian's family had apparently resolved their differences with his future wife. Jenner has even posed for photos on Snapchat with her to-be sister-in-law claiming that they are "friends," but it seems like there is still some bad blood between them.

In a Snapchat video that followed, Chyna revealed that she made her baby daddy's phone number public in order to stop him from texting other women. Watch the video below:
