Former Real Housewives of Beverly Hills star Joyce Giraud has accused current cast mates of 'bullying' Lisa Vanderpump in an exclusive interview with DailyMail.com.

During the latest season of the hit Bravo reality show, Vanderpump has been accused of setting up her co-stars and leaking negative stories to the press by her co-stars Kyle Richards, Dorit Kemsley, Teddi Mellencamp, Lisa Rinna, and Erika Jayne.

But Giraud - who starred in Season 4 of RHOBH - insists the other women are in the wrong.

The 44-year-old model and producer says: '100% they are ganging up on Lisa. And it's horrible to see. Any decent human being can see how terrible it is what the other women are doing to Lisa.'

While Giraud admits that the ill-will towards Vanderpump seems to fluctuate between seasons, she believes the current bout is more 'intense' as Vanderpump was dealing with the death of her brother when filming began.

'This season of bullying is the worst because of what Lisa has been going through. She just lost her brother. She was enclosed in sadness. I don't see how an entire group can gang up on her.

'It was very difficult to see. Very sad to see. People should have rallied around her. Lisa needed support. They kicked her when she was down. She was in a terrible state. She was very vulnerable.'

Giraud knew Lisa was in such a 'state' because the two have become close since they worked together on the show during Season 4.

Scandal: During the latest season of the hit Bravo reality show, Vanderpump has been accused of conspiring to expose her friend Dorit Kemsley for dumping a rescue dog. As a result she has fallen out with Dorit, Teddi Mellencamp, Kyle Richards, Erika Jayne and Lisa Rinna

'Lisa is a good person with a good heart. We are very good friends. Our husbands are friends. My children adore her.'

The RHOBH drama began with the PuppyGate debacle when a rescue pup from Vanderpump Dogs adopted by Kemsley ended up in a shelter.

Kemsley claims the dog wasn't a 'fit' for her home and gave it to a friend who in turn gave it to a shelter following a family emergency. It was the second dog Dorit had adopted and given up.

What happened next has been the center of drama and broken friendships: Teddi Mellencamp claims she was dragged into a plot to expose Dorit by Lisa Vanderpump and two her Vanderpump Dog employees - John Sessa and John Blizzard. Vanderpump denies any involvement.

Most of the cast believed Vanderpump was behind a conspiracy to make Kemsley looked bad.

To make things worse, a story about Puppygate was leaked to an online source and the cast thought Vanderpump was responsible. (Vanderpump denied having a hand in the story.)

Richards confronted Vanderpump about the leaks in episode 8. Vanderpump denied it while swearing on her children's names before kicking Richards out of her house.

The end of a friendship: The Puppygate saga caused firm friends Kyle and Lisa to have a huge falling out

'The minute Lisa swore on her children, the discussion should have been dropped,' Girard explained.

'She swore on her children's lives. No mother would swear on her children's lives.

'I don't think Kyle Richards is being a good friend. Kyle Richards is part of the group ganging up on her.'

When asked why she thought Richards and the other women would turn on Vanderpump, the former Miss Universe Puerto Rico said: 'I think they are jealous.'

'No other explanation. They want to bring the Queen Bee down. There's not a single explanation to bringing someone down after they lost a brother.'

Giraud claims to be an expert on the 'bullying' tactics used by the cast as it happened during her season in 2013 as well.

Good friends: 'Lisa is a good person with a good heart. We are very good friends. Our husbands are friends. My children adore her'; (pictured 2014)

'All the girls were trying to tell me Vanderpump was a bad person. Kyle kept trying to talk bad about Lisa on my season. Brandi (Glanville) even called me and said Lisa is very mean. But I kept saying "I don't see it."'

'And the ganging up is not new. I see it over and over. They are trying to do it to Teddi now, to get her to join them. Look.. there's drama and then there's pettiness.'

Regardless of the 'warnings', Giraud reached out to Vanderpump after the group 'ganged up' on her in Puerto Rico.

'I knew I didn't want to be a part of the show after our Puerto Rico vacation. I called up Lisa to see how she was doing and she said she'd love to have dinner.

'And we had the best dinner. We could have had a lot of fun on the show. And I regret we weren't friends on our season, maybe I would have had a different experience. Because all the girls tried to tell me she's not a good person.'

And since the two have become such bosom buddies, Giraud has had many discussions if Vanderpump should remain on the show after the latest dramatic row.

Familiar: Giraud claims she was subjected to 'bullying' tactics by the cast as during her season in 2013

'We've had multiple discussions about her leaving. I can't say where's she's leaning as a friend., but yes... she's considered it. But I'm her friend, I can't say about that.

'But as a friend, I think she should not do it anymore. She's way too successful. She likes to empower other people. Look at how much she has going on in her life. It's incredible.'

Giraud - who gave the interview during her vacation in the Caribbean - reiterated that she is not interested in returning to the RHOBH franchise.

'I knew mid-season, this was not the right platform for me. I'd rather swim with sharks here than swim with those sharks again.'
