The teaser showed the pregnant star yelling into a phone as she angrily asked Kris Jenner's son if he was still sending text messages to other women.

At this time, it is still unclear what could have sparked Chyna's jealous rant. The clip also showed the Hollywood star locking Kardashian out of their house. However, the engaged couple managed to overcome the said relationship drama.

The said scene may have also sparked Kardashian's previous decision to remove Chyna's pictures from his social media accounts. Several reports have speculation of the couple's potential separation following the said incident. The reality star may have previously swiped his social media accounts clean given Chyna's cheating accusations, as stated in the same report.

Although a source has previously shared with E!News that the engaged couple has had small arguments during their relationship. However, Kardashian previously deleted all Chyna content from his social media accounts after she "flipped" on him. The source explained that it was Kardashian's way of hurting Chyna after the painful things that she said.

The source also commented that Kardashian has remained loyal to his pregnant fiancee and that the cheating accusations were untrue. The source made mention of Chyna's past experiences where an ex-boyfriend may have cheated on her. The said situation may have made her "very paranoid."

Meanwhile, the two stars have already reconciled shortly after their huge fight. The source confirmed that Kardashian and Chyna have returned to being in love with other.
