PARIS HILTON’S wedding on Thursday would be just as over-the-top as you could have imagined — and possibly more so.

The 40-year-old DJ knows how to party, which is why she’s preparing to throw the ultimate celebration for her nuptials to fiancé Carter Reum.

The “Cooking With Paris” star promises a weekend to remember, worthy of her first trip down the aisle after three prior engagements. “It’s gonna be, like, a three-day affair. We have a lot happening,” she said on “The Tonight Show” with Jimmy Fallon.

She also confirmed that the whole trip to the altar will be filmed for a Peacock docuseries called “Paris in Love.” “I wanted fans to see that I found my Prince Charming and my happy fairytale ending,” she told Fallon.

Paris reconnected with Reum, 40, in November 2019 after knowing him “for 15 years,” and their relationship only grew stronger over the pandemic while she was unable to travel as she normally does, she told People, “The silver lining is that I get to be with my pets and my boyfriend. We have gotten so close. The amount of time we’ve had together is what would normally take five years!”

“I am excited about this next chapter and having such a supportive partner,” Hilton told Vogue after Reum proposed to her on a private island in February. “Our relationship is one of equals. We make each other better people. He was absolutely worth the wait!”

If Paris’ wedding is anything like her engagement ring, then it will be filled with meaningful touches and details galore. The dazzling rock, which is “inspired by the Grand Palais in Paris,” is a massive emerald-cut diamond designed by jeweler Jean Dousset — the great-great-grandson of famed French jeweler Louis Cartier — flanked with multiple smaller diamonds and inscribed inside with a “P” and a sapphire.

Paris and her fiancé escaped to Las Vegas for a joint bachelor and bachelorette party, where they celebrated in true Paris fashion.

The couple, along with their closest family and friends, flew in on a private jet, where the couple climbed in a red Rolls Royce that led a fleet of town cars to their destination. The group stayed at Resorts World LV, partied at Area 15 and hit up Zouk Nightclub as well.

Festivities consisted of clubbing, dancing and ziplining — and everyone went home with tons of custom merchandise.

In honor of Paris’ “happily-ever-after” fantasy coming true, she enjoyed an Alice in Wonderland themed-bridal shower ahead of her special day. The event was thrown by her mother, Kathy Hilton, sister Nicky Rothschild, and friend Tina Chen Craig.

Guests were treated to wonderland-inspired desserts and were greeted by the Mad Hatter himself. There was also a champagne vending machine.

The bash was hosted in Kathy’s home. The “Real Housewives of Beverly Hills” star invited Paris’ aunt Kyle Richards, as well as a few of her castmates including Dorit Kemsley, Garcelle Beauvais and Crystal Kung Minkoff.

For a second Alice in Wonderland-themed event, Hilton treated friends to an event in her backyard that included cookies and cans of sparkling water featuring the couple’s faces, and a toilet paper wedding dress competition.

When Paris made her appearance on “The Tonight Show,” she said the only part of wedding planning she had undertaken was the dress selection.

Her mom Kathy Hilton is taking the reins. “She’s not the fancy person people might think,” Kathy said. “The truth is, she’d be happy with white teddy bears and unicorns hanging from the ceiling.”

The mother of the bride confirmed that the wedding was sure to “be beautiful and classic.”

Kathy revealed that “something old” will be sewn into her daughter’s wedding dress. “I am having something sewn into her wedding dress that’s going to be a big surprise … it’s going to be very special,” she said.

The bride’s younger sister Nicky wore a Grace Kelly-inspired Valentino gown during her 2015 wedding to James Rothschild.

In the “Paris in Love” trailer, the star tries on a wide variety of styles, from floaty and princess-y to full-coverage lace.

You would think that the woman who owns a US$65,000 crystal-covered Birkin bag has it all, but there’s still plenty to register for. She and Reum have registered for upwards of US$60,000 worth of home furnishings and more at Gearys Beverly Hills.

Even a Hilton can have trouble securing a great location: “All the venues are getting booked up. I’m gonna end up getting married at Chuck E. Cheese or something,” Paris joked in the “Paris in Love” trailer.

Kathy revealed that Paris would stay over at her family’s house the night before the wedding. “She must spend the night here with us the night before. That’s a tradition,” Kathy said.

Latest reports said the heiress would marry at the Bel-Air estate of her late grandfather, hotelier and philanthropist Barron Hilton. The Bel Air mansion in Los Angeles belonged to the Hilton family for 60 years but sold to former Google CEO Eric Schmidt for US$61.5 million in May.(SD-Agencies)
