Donato and Briones, who both appeared on 2011's thirteenth season of Big Brotheron CBS, wed at the Newland House Museum in Huntington Beach, CA, on Saturday, Peoplereported.
"Truth be told, I really didn't like him at first. I thought he was a little troublemaker. But we became friends, and although I didn't like him like that, it just grew," Donato told People.
"After the finale, we became inseparable. We got to know each other really well, and we fell in love!"
Briones competed on Big Brother 13 as a first-time houseguest while Donato was a returning houseguest. Donato had previously appeared on the eighth season of the show alongside her father "Evel" Dick Donato.
"We wanted something that was a good reflection of who we are," Donato said of their bohemian-style wedding. "We didn't want a traditional ceremony, because that's not exactly us."
The bride reportedly wore a vintage-style gown from BHLDN after looking at "maybe 1,000 dresses."
"It's vintage but modern with little sequins in copper. I'm sort of a hippie girl. I saw the dress and immediately knew it was the one. I went into one bridal stores and I felt like the dresses looked like down comforters. So when I saw this, I was like, 'Perfect.' We had a much harder time looking for something for Dominic to wear," Donato explained.
Briones sported a plaid purple shirt and cardigan sweater with dark purple pants from the Gap and an off-white bow tie. To complement his outfit, he wore matching Converse shoes.
Although the newlyweds, who got engaged last August when Briones popped the question at the St. Louis Zoo, won't be taking off on their honeymoon any time soon, they are planning to go on a trip eventually.
"I've always wanted to go to an airport and take the next flight to wherever it goes out," Briones told People. "That's what we're going to do."
"I don't care where we go for the honeymoon," added Donato. "All I care about is that I married my best friend, and we're going to share our lives together. We mesh so well. We don't like being away from each other. We love being around each other so much. That's enough for me. I couldn't be happier."
