Anyone who’s watching Season 9 of The Real Housewives of Orange County knows that newbie Shannon Beador isn’t exactly gelling with Heather Dubrow. We’ve had “Chairgate” and the hoedown showdown drama — not to mention last night’s beef-squashing lunch — so when we spotted some recent Twitter drama between these ladies, we weren’t exactly surprised.

“I sent Heather our holiday card, but didn't receive hers. Must have been lost in the mail... #RHOC,” Shannon wrote on Twitter, stretching her passive aggressive writing muscles. To that, Heather had only one thing to say: “We don’t send out cards.”

During last night’s episode — Season 9, Episode 7 (“Choke-Lahoma”) — both Shannon and Heather gathered their adorable families together to take some portraits. While Shannon was obviously getting her Christmas card shot ready, it seems Heather was just taking photos for kicks and giggles.

Heather and Tamra have had a tough time getting along so far this season and it looks like things are only going to get worse later on this season. We don’t want to judge where these ladies stand with each other just by this one Twitter exchange, so guess we’ll have to wait for the reunion special to see how things are really going!

Do you think these ladies will ever get along? Hit the comments and sound off!
