Bravo's The Real Housewives of Beverly Hills has provided its audience with plenty of jaw-dropping, goosebump-inducing moments over the years.

. But few have come close to the rocky territory that was Lisa Rinna and Kim Richards. When the ladies vacationed in Amsterdam in season 5

Lisa is a known pot-stirrer in RHOBH. She entered the show in season 5 with no plans of holding back, always ready to discuss the most controversial situations regarding the other women.

Kim isn't her first or only target for discourse, but viewers will agree that this particular fall-out is one for the history books.

Kim's battle with alcoholism was well-worn by season 5. Viewers knew practically all the ins and outs of her relationship with drinking,

and how it had negatively impacted the dynamic between her and her sister, Kyle. Lisa's entrance to the show sees what comes across as feigned concern for Kim's situation,

When Brandi ushers Kim back into her chair, Lisa takes her opportunity and gets back on her feet to assert her dominance.

Two intense personalities clashed, everything around them became hazy, and all bets were off. It's safe to say The Real Housewives of Beverly Hills has never been the same since.
