The reality stars married Saturday atop the AT&T Center in downtown Los Angeles, where the redheaded bride arrived via helicopter.
"She wanted to arrive like a big celebrity," celebrity wedding planner – and host of WE tv's My Fair Wedding – David Tutera tells PEOPLE. "The guests will watch her arrive on live camera before she walks down the aisle, which to me is one of the most over the top processionals ever."
Being over the top is nothing new to Reilly, 27, who met Villegas, 32, while filming Big Brother 12 in the summer of 2010. Their alliance – known to fans as "Brenchel" – turned romantic early on in the season. And the couple was engaged less than a year later before returning to Big Brother 13, which Reilly won.
"We get to start our future together," Reilly told PEOPLE after winning. And their future started with all the "glitter and sparkle" Reilly had hoped for while planning their nuptials.
A Sunset CeremonyReilly walked down the aisle at sunset in a floor-length, silver-sequined Missoni gown with a sweetheart neckline that was "not at all a bridal gown," says Tutera.
"She's more comfortable in evening wear that you would wear down a red carpet than a white carpet," he says of the bride, who was accompanied by bridesmaids – including Big Brother's Chelsia Hart – in short, gold-and–silver sequined cocktail dresses with chiffon trains.
After the ceremony officiated by Big Brother's Matt Hoffman, the groom – dressed in a white dinner jacket with black tuxedo pants – and his new bride were lowered in to the all-glass reception room using skills they learned while taking circus classes.
A "Sparkly" ReceptionFellow Big Brother couple Jeff Schroeder and Jordan Lloyd were among the 130 guests at the celestial-themed reception that included all-white flower centerpieces with faux diamonds in the orchid heads, silver chairs with custom silver sequence chair backs and tables with silk, pewter underlays with silver sequins overlays that "looked like the patterns of glittering stars."
"She wanted to have something that made her feel like she was in the sky," Tutera said of why he chose the downtown venue. "I wanted one of the highest locations in Los Angeles, giving her the ability to be the closest to the stars."
Guests dined on a buffet of arugula and tomato salad, grilled chicken breast with balsamic glaze and grilled corn and black bean salad before enjoying sparkly silver and blue cupcakes from a display designed to look like a wedding cake, and they were treated to a performance Tutera referred to as "a retrospective of dance throughout time" that featured the bride in a white sequined tutu and the groom in bedazzled loafers and a sparkly shirt.
Reilly and Villega's big day will be showcased on the Dec. 15 season finale of My Fair Wedding: Unveiled on WE tv, which airs Saturdays 9 p.m. ET.
