Nothing brings out the ugly like a “Real Housewives” reunion special!

And the dirt that’s flung on Tuesday’s “The Real Housewives of Orange County” reunion reveals that one housewife has accrued a reputation for treating the production crew terribly.

If you thought Alexis was ganged up on in Costa “Not Mexico” Rica, wait until you see the ladies out her as a diva who mistreats the staff behind the scenes.

“I have never seen someone treat a crew the way you treat this crew,” Heather fires off to Alexis during the screechfest.

“She treats them like trash,” she added, as the other wives chime in, “She’s rude” … “It’s hideous.”

Watch the Clip Above for Alexis’ reaction and reply to the accusation.

“It was crazy, as always … Reunions never let the fans down,” says Gretchen Rossi of this season’s reunion special, which is one “Housewives” showdown you’ll never forget.
