Kelly Sends Tamra Over The Edge On 'RHOC': 'I'll F*cking Kill You!'

True turmoil is about to get started! But this time around, the feuding isn't between Vicki Gunvalson and Shannon Beador (surprisingly).

This week on The Real Housewives of Orange County, the ladies jetted off to Ireland to explore Meghan King Edmonds' heritage and try their luck of the Irish.

But on a pub crawl during their first afternoon out, too much drinking and petty joking led to a nasty exchange between Tamra Judge and Kelly Dodd.

"Sometimes you're a little bit crass," Tamra told Kelly of her mean-spirited pestering and practical jokes. "You need to stop. It's not funny, it's rude."

Exasperated over Tamra's scolding, Kelly cut in with a whole new slew of accusation: "If I say something to you, you go tell every single person."

"I've kept your f*cking secrets!" Tamra shouted back, the volume escalating. "I didn't even tell Heather when you said that you had your real estate agent check into the loan on her property."

Shoving Kelly over, Tamra growled, "Don't talk about my daughter, I'll f*cking kill you! How dare you!"

After some consoling from Shannon and Vicki, Tamra managed to calm down some, but the damage had been done.

With Kelly on the outs, the rest of the ladies tried to salvage their first day in Ireland by enjoying a traditional Irish Hooley Night.
