VIDEO: See the Ridiculous Reason Brandi Glanville Slapped Lisa Vanderpump on Real Housewives

This season of Real Housewives of Beverly Hillshas been filled with violence and drama, but this might be the most bizarre assault yet.

While out in Amsterdam, one of the women referenced The Love Boat, which inspired Brandi Glanville to try and reenact tropes from the series. Namely, kissing and slapping. We've already seen what happens when Brandi tries to reenact soap opera moments with actual soap stars, so it's no surprise that when she tried to do her best Love Boat impressions with none other than Lisa Vanderpump, things went south. Fast.

Hannah Montana stars: Where are they now?

Lisa, of course, refused to kissed or be slapped, and Brandi, of course, slapped her across the face. "No, that's wrong. Stop it right now," Lisa said. "I don't like that. It's like throwing a glass of wine in someone's face."

The fallout from the slap will surely continue next week and when you're watching remember: This is all because of The Love Boat.
