The strangest thing about the feud between Real Housewives of Beverly Hills’ Adrienne Maloof and Brandi Glanville wasn’t the name-calling or the fur flying, both par for the RHoBH course. The oddest thing was that, for a while, we had no idea what they were fighting about!

On a December episode of RHoBH, Brandi said something about Adrienne that made Adrienne call her a liar and threaten a lawsuit. Adrienne’s then-husband Paul Nassif also called her a bitch. So what did Brandi Glanville say about Adrienne Maloof that started this whole war?

Bravo didn’t air the actual accusation, but Wetpaint Entertainment revealed the source of the drama: Brandi claimed that Adrienne and Paul used a surrogate to have their three children, while Adrienne insisted that she had them naturally. Adrienne has since revealed her twins, Christian and Colin, were indeed carried by a surrogate. She has not, however, forgiven Brandi in the least, according to a recent interview with Life and Style.

And there you have it! Where this feud goes from here is anybody’s guess, but if you’re looking for the spark that got this Real Housewives of Beverly Hills’ fire raging, there you go!
