'Darcey & Stacey' twin stars had a blowout argument over 'twin wedding' fallout

The Silva sisters, Darcey and Stacey, are inseparable - or are they? Darcey, 48, accuses her sister of being "high-strung and condescending" as she plans her wedding to fiancé Florian Sukaj in the PEOPLE exclusive footage from Monday's episode of Darcey & Stacey. She divulges, "The tension between us is not because there is no twin wedding. That's not the point. Stacey is deflecting and not looking at the bigger picture. I think the real tension here is that she's completely changed since she started planning her wedding." Furthermore, following her breakup with her fiancé Georgi Rusev, the 90 Day Fiancé star admits to hiding her actual sentiments about their plans for a double wedding from her sister. "Well as soon as I said goodbye to Georgi, I was actually relieved that there wouldn't be a twin wedding," she says. "But I didn't voice it to you guys because I didn't know how it made you guys feel." "You really felt that we cared so much about the twin wedding over your life and your relationship?" asks Stacey in a snap. She adds, "I'm surprised that you thought we cared more about the twin wedding than your relationship," expressing concern that Darcey believed she was placing their big day ahead of her happiness.

Stacey Silva confesses to her belief that her sister is "hiding beneath this facade that everything is okay" in a confessional. "I know that it's not easy to break off an engagement in a twin wedding," she admits. "So I know there's hurt down there and I know she's taking all of her anger out on me." As the tensions between the sisters increase, Stacey tries to make up by expressing, "[I'm] really sorry that I'm projecting negativity on you with the twin wedding," during their smoothie date. Darcey states again, "I was actually relieved that I wouldn't have to do a twin wedding. Did you not hear me?" to which Stacey responds, "You're nasty." "It had nothing to do with you. I didn't want to have a twin wedding," Darcey elaborates. Nonetheless, both sisters are still dealing with the drama, and Stacey revealed that Darcey is "so rude and nasty. I can't believe this. So f—ing nasty. Wow." Lastly, Darcey & Stacey airs every Monday at 8 p.m. ET on TLC.
