'Vanderpump Rules' Stars Violent TV Catfight Was REAL

The bitchfight on this week's episode of "Vanderpump Rules" was not just reality TV BS ... we've learned one of the stars ran to the cops afterward ... fingering her castmate.

Stassi Schroeder
accuses Kristen Doute of sleeping with her ex-boyfriend ... calling her a "dirty f**king whore" ... then hauling off and smacking Kristen in the face. She also douses Kristen with a drink -- while the rest of the cast looks on.

The fight was not scripted ... and Kristen was so enraged she was gunning to get Stassi prosecuted and filed a police report.

But we found out the criminal case hit a dead end ... cops needed a follow-up interview but Kristen was uncooperative.

Lisa Vanderpump -- who employs both Stassi and Kristen at her restaurant -- tells TMZ the women have since made up telling us, "I know that Stassi was very sorry and regretted it. I made Stassi apologize to Kristen and hope that they could move forward."

Now everyone can be their bitchy selves again.

Lisa Vanderpump's Husband I Was Attacked with a Concrete Chipper And Then Extorted

Lisa Vanderpump's rich husband Ken Todd says he has a concrete reason to file a fat lawsuit ... claiming a construction worker attacked him with a cement chipper, then tried to extort him for $50,000.

Todd filed the lawsuit against Kevin and David Cazaref, claiming the two brothers had been hired to do construction work on Ken's P.U.M.P. Lounge in West Hollywood.

Ken says he observed Kevin (a man twice his size) using a concrete chipper unsafely last week, so Ken confronted him and attempted to show Kevin how to use it properly.

Kevin must have taken offense ... because Ken says the worker then "became enraged, grabbed and violently hurled the heavy concrete chipper" at him ... hurting his hip, leg, and knee.

According to Ken's lawsuit, Kevin's brother David approached threateningly in Kevin's defense -- at which point nearby police officers became involved.

No arrests were made, but Ken says the brothers later contacted him in an attempt to shake him down for $50,000 in exchange for keeping quiet about the altercation.

Ken's now demanding unspecified damages from the brothers, suing them for assault, battery, extortion, and more. We reached out to the brothers for comment, so far no word back.
