Carlton Gebbia and Kyle Richards have had under-the-radar friction thus far on Season 4 of Real Housewives of Beverly Hills. But anything we've seen between them onscreen pales in comparison to what Carlton says about Kyle this week on Watch What Happens Live.

While a guest on WWHL this week, Carlton is asked why she doesn't judge Brandi Glanville for calling her the c-word but is very hard on Kyle asking her about witchcraft.

"Because with Brandi, I understand her, we have a friendship," Carlton explains. "So her calling me the c-word is coming from, I think, a place of friendship, which I do have with her." That's a weird friendship.

So why doesn't she give the benefit of the doubt to Kyle as well? "Because up that point, there had been many little innuendos and digs [from Kyle] that were passive aggressive, and just, you know, toxic," Carlton says. "So I don't have patience for morons."

Whoa! Talk about incredibly harsh of Carlton to call Kyle a "moron." This is especially surprising since we've seen Carlton and Kyle seem to bond on the show, as in this week when they discussed Kyle's role in Halloween. So it seems that Kyle hadn't realized how much Carlton dislikes her.

As you might guess, Kyle had a response to Carlton's comment. "Dear Carlton, wouldn't it be easier to not accept my invitations, then to come & be nice to my face and then speak badly about me?" Kyle tweets. Good point, Kyle.

Are you surprised by what Carlton is saying about Kyle, especially since she is nice to Kyle's face?
