Joyce Giraud is sick of her Real Housewives Of Beverly Hills co-stars constantly sticking up for Brandi Glanville.

In the new preview for Monday’s episode, Joyce tries to sway Lisa Vanderpump to her side following the dinner party from hell.

“You’re very close with Brandi and I understand that. With that being said, I feel like Brandi for a long time has been attacking me and you guys just make excuses for her,” Joyce confides to Lisa.

“Look, I’m not making excuses for her, but she is my friend. One thing I can say is that she has been going through a really tough time lately,” Lisa says.

“That’s an excuse,” Joyce bluntly replies.

Talking to the cameras, Lisa says she thinks Joyce is “a good girl” but needs to “give Brandi a little bit of a break.”

“You’re not responsible for her actions,” Joyce tells Lisa. “You’re not her mom. You’re just her friend.”
