Real Celebrities vs. Real Housewives: Smackdown Edition

Some people at Bravo wanted the RHONJ star and the actress to take a photo together, but Vergara passed. And Guidice was not pleased, saying Vergara should've been nicer because she has an accent and is an immigrant. Or maybe Sofia knew exactly who she was dealing with and didn't want a table thrown at her.

During a taping of Late Show With Seth Meyers, Frankel told the host that Stewart "doesn't like me" and "never really has," adding that "she's never missed the opportunity to say something negative about me or my products." Well, let's see; there was that time Martha called Bethenny a "pest." Another when she described her as "unlikable." And she called Bethenny's Skinnygirl margaritas "horrible."

Do we really need to explain this one? A married LeAnn cheated with Brandi's then-husband, Eddie Cibrian, back in the day and then the two left their respective spouses for one another. Their feud is timeless, classless, and often documented on social media. Like all the good ones.

Paparazzi were interviewing David through his car window while he was sitting in his Mercedes. RHOC's Kelly was in the vicinity, noticed it was David Foster (Yolanda Hadid's ex), opened his passenger door, started to sit inside, and laughingly yelled "you're gonna have another housewife!" A very startled David then asked her to please get out of his car, Kelly replied that she was just joking, but it was pretty obvious her humour wasn't well-received. The best part about this is that it was all caught on camera.

David's people later released a statement saying, "In today's environment, what Kelly did was careless, inappropriate and disrespectful. David drove away in his car, alone and shaken. The video and her remarks speak for itself."

Before Brandi and Eddie came RHOBH's Camille and Kelsey. It was in the first season that Camille revealed her husband wanted out of their marriage, probably because while she was filming RHOBH, he was in New York doing a play, and embarking on a new relationship with a flight attendant. The actor eventually married his airplaning rebound two weeks after his and Camille's divorce was finalized and there aren't enough UGHs for this guy.

Leakes had "one enemy" on her season of The Celebrity Apprentice: Jones. She told reporters, "Star Jones has got it in for me, but it's all good. I'm OK with it. There are a lot of people who don't like Star, so I won't be the only one."

The RHOA star added that the reason for the clash is simply that they're very different. "She's a piece of work. Anyone who sits around all day and says all her friends are doctors and lawyers and A-list celebrities — cut the BS, I don't have time for it."

Things got tense during an episode of Watch What Happens Live between the actress and former co-host of The View and the RHOA star. Shepherd called Moore "Kendra" several times and anyone who's had their name repeatedly said incorrectly will get the point of contention. But it was when Sherri offered Kenya some words of wisdom as to how she should treat her fans that where the disdain could no longer be hidden. The two went at it after on Twitter and, yeah, that's about right.

They may be half-sisters but that doesn't mean they always get along. Due to family dynamics, mainly their husbands' competing businesses, there's been tension and the women sided with their respective partners. Kyle was even uninvited to her niece Nicky's wedding. Damn.

These two got into a beef ... over an Hermès Birkin. NeNe's customized bag, complete with all its NeNeisms did not sit well with Williams, who tweeted about the RHOA star "defacing" it. Never to back down from a fight, Leakes tweeted back, "Don't come 4 me WENDELL," and linked to a blog post in which she tells Wendy to "be scared." Honestly, though? It's her bag, she can do what she wants with it. (And, FYI, it was for charity. Guess NeNe will just have to make do with one of her other Birkins.)

During their season of The Celebrity Apprentice, Ziering admitted he pushed people's buttons and purposely got on their nerves "to survive." But there was no one he loved bugging more than Brandi, who couldn't stand it. No love lost there.

In that same season of The Celebrity Apprentice, another feud was brewing. Kenya reportedly stole Vivica's cellphone and tweeted a lot of nasty things out AS Viv. Fox found out, confronted Moore in the boardroom, and Kenya was fired, giving Vivica the last laugh.

It was in 2016 that Romijn took to Twitter to say that social media models are not "true supermodels" — which lit a fire under the former RHOBH star, whose children arguably fall into that category. Granted, Rebecca was referring to the industry itself and not the people working in it, but the damage was done and the mama bear's back was still up, despite Romijn's clarification.

Technically, this was three years before Rinna began her Real Housewives run, when she was purely known as a soap opera actress, but we're counting it anyway. The two didn't get along on The Celebrity Apprentice, and things only got worse after Rinna's elimination, which she blamed on Jones. Lisa reportedly sent Star aggressive tweets and emails for months, and it got to a point where the former View co-host had to take legal action to quiet her down.

Back in 2015, the two attended a dinner held by the Qatari ambassador to the U.S., and Mohammed Jaham Al Kuwari had no idea what he was getting into. According to Page Six, the Countess was chatting with her host about visiting Qatar and him appearing on The Real Housewives of New York when Martha interrupted.

"Stewart leaned in and whispered, 'You don't want to do that. It's lowbrow, very B-list,'" claimed a source. Luann's response: "Martha, I can hear you." Um, she knows; that's why she said it loud enough for her to hear. Stewart later said it was all in good fun and she was only kidding but de Lesseps was pissed nonetheless.

The RHOBH star put sexist double standards on notice after the Dancing With the Stars head judge called her salsa routine "raunchy."

"He's totally entitled to his opinion," Girardi wrote in a blog post for People. "But I didn't feel that was the case and I'm also allowed to disagree." She added that it's the "price you play for owning your sexuality and not being afraid and being fearless and being yourself as a woman." Preach, girl.

That time NeNe called Kim Zolciak-Biermann's daughter "racist trash" after an old Snapchat video surfaced of Brielle in Leakes' home, where roaches can be seen on the floor. Um ...

Hadid has been open about her struggle with Lyme disease so when Osbourne focused on her own struggles with the illness in her memoir, writing that "it seems like the trendy disease to have right now, and I'm tired of seeing sad celebrities play the victim on the cover of weekly mags," Yolanda was not pleased. Kelly later clarified that she wasn't referring to Yolanda; hopefully it's water under the bridge.

Andy Cohen revealed in his memoir that while the supermodel is a fan of RHOA, she "can't stand" Kenya. Ouch.

Things got heated during a 2015 taping of The View and NeNe felt like Joy and Raven were "throwing a lot of shade" her way.

She may be a SURver, far from a Housewife, but the radio host called Lala a "full-blown hooker" in light of her "modelling" trip to Italy, but Kent was more than happy to fire back, tweeting about Jenny's start and posing for Playboy. Burn.

OK, he's not technically a housewife (or real) but when Maher called the POTUS "The Real Housewife of Pennsylvania Avenue," it made total sense.
