For over a decade, reality TV has been ruled by the lovable dysfunctional family. From The Osbournes to Keeping Up With the Kardashians to Hogan Knows Best to Run's House, viewers have developed a thing for drama-riddled kinsfolk lacking in boundaries and steeped in wacky, fantastical scenarios like sex tapes, whirlwind pop careers, and just plain fame and fortune. And while The Girls Next Door weren't exactly a family, they were, by all accounts, a sort of artificial sisterhood that shared a hybrid Daddy Warbucks/Prince Charming: Hugh Hefner.

Airing between 2005 and 2010 on E!, the reality show chronicled the very pink, very blonde, very sexy lives of Playboy magnate Hefner's three most famous girlfriends: Holly Madison, Bridget Marquardt and Kendra Wilkinson. It was a hit for the network and the Playboy brand, spawning a number of television spin-offs and product endorsements. It even loosely inspired Anna Faris' 2008 rom-com, The House Bunny. For a few years, the series and its glamorous, buxom stars were at the center of pop culture.

Unfortunately, according to an interview with PEOPLE published May 19, despite their apparent friendship on the show, an off-camera rivalry was brewing within the girlfriends' glittery circle—namely between Hefner's ambitious main squeeze Madison and his sportier, hip-hop loving girl Wilkinson.

Six years later (and despite the seemingly diplomatic efforts of Marquardt), there's still bad blood between Madison and Wilkinson. For longtime fans of the show, their ongoing clash may have disappointing consequences: While rumors of a potential reunion starring the three former girls next door have circulated for years, even as a plot point on Wilkinson's own Kendra on Top WeTV series, it looks like those dreams may be dashed... for now, at least.

When asked if it would be possible to mend their relationship in order to film a reunion, the reality star was quick to slam Madison. "She wouldn't do that," Wilkinson briskly stated, adding, "because she has too much to hide." As for Marquardt, however, "She has an open heart and we wanna talk things out and clear the air... because we both have nothing to hide."

The revelation came just days after Wilkinson dragged Madison on Twitter in a series of since-deleted vulgar tweets on May 12.

"That b---h [Holly] is in fear now knowing so many of us saw her doing some nasty s---," the reality star wrote, upset over claims the other former Girls Next Door alum had made in one of her books about their shared time in the Playboy Mansion. "She's embarrassed and in shame. She was the clean-up girl. Hollys [sic] job was to get Hef h--- again and clean him up with her mouth."

The same day, she deleted her posts and issued this apology:

However, there's always two sides to a story—in this case, three. On Wednesday May 18, Marquardt also spoke up about the prospects of a Girls Next Door reunion and dished on the status of the relationship between herself, Wilkinson, and Madison. And while she seemed somewhat more optimistic, Marquardt certainly had a lot to say.

Talking to Hollywood Today Live, the horror aficionado opened up about her unique relationship with her former E! co-stars: "It's kind of sad. Like I feel like we have a bond, the three of us. It's kind of like, it's not like a sisterhood, it's not like friends, I mean it is friends, but it's something totally different than any other relationship you could possibly imagine."

Expressing her disappointment over their fractured bond, she continued: "And so in that sense, it kind of makes me sad."

When the subject of Madison and Wilkinson's feud was raised, Marquardt was quick to defend Hefner's former main girlfriend Madison, while remaining rational and empathetic towards Wilkinson, who she revealed she'd recently made amends with.

"I mean, Holly came out with a book and she gave her experience," she reflected, adding that Wilkinson hadn't even read it. "This is what I told Kendra: 'She's writing about her experience and this is how she's reflecting on it and she has a right to do that. And you have a right not to agree with her, but lashing out like this and saying such vile things and stuff isn't really the way to handle it either.'"

It's a good point, albeit likely too late: Madison later confirmed to Us Weekly that yes, she did see Wilkinson's nasty tweets about her and no, she's not all that interested in revisiting the past.

Calling her former co-star's outburst "a little, like, Azealia Banks-y," the Las Vegas showgirl and author shared, "I've written a book, The Vegas Diaries, that's about letting go and moving on. About resolving the past so you can live a future. I've dealt with my demons and I've come out ahead. I can hold my head high and work hard to be the classy and kind person I aspire to be. I want no part of a one-sided argument or feud where one woman lives to demoralize and degrade another woman. For those with unresolved issues, therapy works. You should try it."

It seems that Madison, Marquardt and Wilkinson's issues with one another remain too unresolved for the three to move forward. For now, GND fans must continue to wait for their favorite reality vixens to make up before returning to the Playboy Mansion for a long-awaited reunion.
