'RHOC' Reunion Part 2: Heather Dubrow & Kelly Dodd Go Head-To-Head

Part two of the Real Housewives of Orange County season 11 reunion special was more dramatic than ever, with newcomer Kelly Dodd and show veteran Heather Dubrow battling to the bitter end of the one-hour episode.

When Dodd wouldn't take the blame for her history of coming after Dubrow with vicious comments on the show, Heather spoke up, saying she was disgusted by Kelly's behavior.

Rolling her eyes in return, Kelly scoffed: "You're not the boss. Are you senior staff at Bravo?"

"We're better than this! Our show is better than this!" Heather bellowed back, launching a five-minute session of hurling insults at one another.

Needless to say, it's likely the pair will be busy battling well into season 12.

Later, Vicki Gunvalson's daughter Briana stopped in to reveal a health shocker: she was diagnosed with lupus. Sadly, she hadn't been ruled out for lymphoma yet either, only time will tell.

Luckily, Vicki's daughter isn't a cancer scamming liar, like some people they know (ahem, Brooks Ayers).

In a hilarious twist, host Andy Cohen asked if Shannon Beador if she had ever made a sex tape with husband David. The health nut answered no, but costars Tamra Judge and Meghan King Edmonds quickly confessed that they had.

Even Andy admitted to having one from 15 years ago!

The Real Housewives of Orange County Reunion: Part 3 airs on Bravo Mondays at 8 p.m. ET.
