Porsha Williams' cousin Storm is at war with Dennis McKinley on Porsha's Family Matters, and their ongoing issues have spilled onto social media. Dennis opened up about the root of their quarrel in the latest episode. But after watching it back, Storm couldn't hold back putting Porsha's ex-fiancé on blast. Storm claimed Dennis physically assaulted her during the family trip and sexually harassed her in the past. But Dennis claimed Storm is spewing out lies and is threatening legal action.

Dennis and Storm have a scarred history that dates back to before he met Porsha. In the most recent episode, Dennis admitted to hiring Storm to work at his nightclub a few years back. Dennis claimed Storm was fired because she was late to work and rude to staff. Since the shady termination, Storm and Dennis haven't gotten along too well, despite his relationship with Porsha. Now with Porsha and Dennis working to co-parent their daughter together, Porsha is trying to get Dennis and her cousin to squash their beef. But their deep-rooted issues only instigate the tension that already exists between all sides of Porsha's blended family.

The latest episode ended with an explosive fight between Porsha and Dennis over his issues with Storm. Following the episode, Storm went on social media and accused Dennis of assaulting her during the trip, among other shocking allegations. "Dennis physical assaulted me in Mexico," Storm captioned a tweet. "I’ve been silent long enough. This man has sexually harassed me & now A grown ass 40+ year old man physically assaulted me in Mexico. I’m sick of it!" The tweet included photos showing Storm with visible bruises on her face and neck.

When one fan asked why Dennis wasn't arrested if he hit her as she claims, Storm claimed they tried to. Storm supported her claims with more photos accusing Dennis of assaulting her. In a since-deleted tweet captured by The Shade Room on Instagram, Storm referred to Dennis as a "pedophile" who came on to her when she was just 18 or 19 years old. Storm confirmed she is a lesbian and said she was never interested in Dennis and shared no romantic history with him. Storm followed it up with an Instagram Live saying that she would not be silenced.

Porsha appears to be supporting her cousin while remaining silent on the shocking claims. The social media drama is the latest in a long line of shouting matches, physical showdowns and complete melee. Porsha's Family Matters is an attempt for the former housewife to form a peaceful blended family for her daughter as she prepares to marry Simon Guobadia. But so far, the tension is too thick to sweep under the rug. There might need to be another family retreat to repair all of the damage that's been done. Most recently, Porsha put Dennis on blast and claimed he doesn't pay child support and he bought her a cheap diamond engagement ring.
