Well, she's at it again. To the surprise of no one, Brandi Glanville ruffled a few feathers on Tuesday's episode of "The Real Housewives of Beverly Hills."

And we finally got to witness the moment we've all been waiting for since this season's trailer was released - Brandi slapping Lisa Vanderpump across the face.

"Slap me! Slap me!" said Brandi Glanville on "The Real Housewives of Beverly Hills."

"Okay, I will," said Lisa Vanderpump.

"If you hit me, I'll hit you back," said Brandi.

"Okay. Pick on somebody your own size! Go on, go," said Lisa.

"No, do it!" said Brandi.

"Pick on somebody your own..." said Lisa.

Oh no she didn't.

After a seemingly intoxicated Brandi started rambling about "The Love Boat" for no reason other than the housewives were on a boat, she decided it would be a good idea to act like she was on the show with Lisa.

She wasn't having it, but Brandi decided to go ahead and playfully smack her anyway. And we gotta say, we weren't expecting Lisa would react quite like this.

"No, no. That's wrong, that's wrong, stop it right now. No, you're wrong," said Lisa.

Yeah, wow. It sounded like she was scolding a child rather than dealing with an out of control middle aged woman. Which actually sounds about right when you think about it.

But not everyone else took the slap nearly as well. As Yolanda perfectly put it later in the episode, "What do you mean you slapped Lisa Vanderpump in the face?"

And a writer for Bustle agreed. "Brandi does a lot of instantly regrettable things without thinking first, but this was not OK. This was so not OK. It didn't seem to be a very strong, powerful, or painful slap, but assault is still assault, even if it's a joke."

Well, we guess Brandi had to graduate from throwing wine at people at some point, right?

You can catch the rest of the Slapgate fallout on the next episode of "The Real Housewives of Beverly Hills" Tuesday on Bravo.
