The latest episode of Real Housewives Of Beverly Hills revealed a dramatic showdown between the two after Kyle accused Lisa of planting negative stories to the press. Ken stepped in to end the row by yelling 'goodbye Kyle!' before kicking her out of their home.

Kyle, 50, referenced the argument and mocked Ken by shouting she was going to 'order a Goodbye Kyle on the rocks' outside while wandering past the front of his restaurant, SUR.

Kyle even got her friends involved in the Instagram video as she asked one 'What do you want to drink?' and the answer was 'I'll have a tequila with a side of Goodbye Kyle!'

The barbs didn't stop there as the ladies kept shouting the now infamous catchphrase adding an English accent to imitate Ken.

And as they were dropped off home, each member of the party got a farewell in the vain of 'goodbye Kyle'. Kyle's close friend Faye Resnick was happy to receive a 'Goodbye Faye' from the group.

The Uber driver even got in on the action by shouting each passengers name as they exited the vehicle.

Not to be left out, RHOBH cast mate Lisa Rinna piled in on social media on Friday morning. She filmed her husband Harry Hamlin sitting at their kitchen table before shouting 'goodbye Kyle!'

Lisa then had her mother Lois film another version of what is now being called the #goodbyekylechallenge.

While the mockery is a source of entertainment for Kyle and Lisa, not everyone is amused.

A production source from Bravo told DailyMail.com: 'This may seem funny to some people but this is bullying by our cast. The cast clearly want Lisa off the show and have gone beyond the production calendar to make sure they are targeting her off the show too.'

The insider maintained that the other cast members - including Teddy Mellencamp, Erika Jayne, and Denise Richards - aren't happy with fans who are taking Vanderpump's side.

'This comes from a cast who are concerned that the fans have turned on them and are now on Lisa’s side. Even Kyle Richards is being criticized and she doesn’t handle criticism from viewers well.'

The source went on to explain that this front against Lisa is distracting from the original source of contention and even other storylines.

'What is absolutely crazy is they have all forgotten who the real villain is here. It’s Dorit. She’s the one who abandoned two dogs. These women clearly have their priorities wrong,' said the source.

'This storyline deflects from what is really going on – we should have captured the lawsuit that Mauricio and the Agency is facing and the ongoing money troubles of PK, Dorit’s husband. These are far juicier than the current storyline. I mean our team had their mouths drop open when Dorit was chased around the pool and called a ‘cheap b*tch’ in the Bahamas for an outstanding debt.'

Even the driver! The Uber driver even got in on the action by shouting each passengers name as they exited the vehicle

The epic feud between Kyle and Lisa began on the episode titled Showdown At Villa Rosa when Kyle confronted Lisa about rumors that she leaked harmful stories about their friend Dorit Kemsley.

'Maybe you care more about your image than your friendships,' Kyle exclaimed.

Lisa stormed away as she told Kyle to show herself out of her Villa Rosa estate in Beverly Hills.

Ken was clearly upset at Kyle after she admitted to believing that Lisa supplied the tabloid story about Dorit adopting a puppy that ended up in a kill shelter.

'You're not her friend! You are not her friend!,' Ken shouted as Lisa said that she wasn't going to admit to something she didn't do.

'I'm done with you, too. Kyle, I'm done,' added Lisa who also swore on her children's lives and the life of her beloved dog Giggy that she didn't give the story about Dorit to a gossip website.

'She would never say something like that about you. You're a f***ing liar! You're not my friend or her friend, so you get out. Please go. Please go! Go join the gang,' Ken yelled at Kyle.

Lisa came back to calm down Ken as Kyle said she was there as a friend to tell her how it looked to the others.

'You came here to tell me I'm a liar,' Lisa told her.

'Good-bye, Kyle!,' Ken said as he marched upstairs.
