"Our wildest dreams came true today -- we're married!" Jessica and Cody, who are also expecting their first child together, toldPeople in a statement.
"Being surrounded by our closest family and friends and sharing this special day with them was all we ever wanted. We are so lucky to have found each other in the most unconventional of ways but we did. We found our forever in each other and can't wait to begin this new chapter of our lives."
Cody, 33, and Jessica, 27, reportedly wrote their own vows and became man and wife in front of less than 100 guests, including their formerBig Brother castmates Mark Jansen and Elena Davies as well as former The Amazing Race Racer Conor Daly.
The couple said, "I do," during an outdoor ceremony at The Chateau Le Dome at Saddlerock Ranch in Malibu, CA, according to People.
"Fall in L.A. is just so gorgeous out, so I wanted to be dancing under the stars all night long," Jessica shared. "I wanted for it to be dripping in flowers, and string lights and lots and lots of candles. I wanted it to look just very romantic. Like a daydream."
Two seats were sweetly left empty for Cody's brother Dylan, who had passed away, and Jessica's beloved deceased father.
Cody reportedly sported cowboy boots with his tuxedo, while Jessica donned a form-fitting silk gown with a dramatic train designed by Mark Zunino. Jessica also showed off her unique tastes by carrying a bouquet made entirely of black orchids.
Cody's daughter, six-year-old Paisley from a previous relationship, served as the flower girl in their wedding, wearing a pink ballgown and a flower crown on the top of her head. The bridal party reportedly wore black, just like Jessica and Cody's guest list.
"I know that's very untraditional, but I like the picturesque feel of it all," Jessica said of her wedding's color palette.
Big Brother's head of casting Robyn Kass reportedly officiated the wedding because Cody said he and Jessica "wanted it to be somebody that was a part of the special process that even brought us here."
"I'm thrilled to have officiated Jess and Cody's wedding," Robyn told the magazine. "I'm just so happy for them."
The pair's reception reportedly featured dinner catered from Texas Road House -- which is Cody's favorite restaurant -- a donut wall, a popcorn installation, a four-foot-tall cake, an open bar, and late-night pizza.
For their first dance as a married couple, Jessica said they waltzed to "Shut Up and Dance" by Aaron Watson because Cody sang that song to her when they were in the Big Brother house together last summer.
"We danced to it, and, it just always sat in the back of my mind as one of our special moments," Jessica explained.
"There was a long time in our relationship where everything we knew about each other, the outside world also new," Jessica said of their time on Big Brother together.
"If you were a live feeder, there were no secrets. It wasn't until we finally got some alone time outside of the house where we could start getting to know each other beyond what everyone else knew, and I think that was pretty special."
Jessica and Cody will now embark on a honeymoon to Bora Bora before they settle into their new house, which is reportedly currently under renovation in Cody's home state of Texas.
"In five years I am going to be on baby probably number three and exhausted. And, hopefully still pretty," Jessica joked when asked what's in store for these happy newlyweds.
"I mean, no matter what we do, we're both going to be successful at it," Cody added. "So, I just don't know what those things are yet. But, whatever it is, we're going to be successful. And, we're going to have good, healthy, strong family."
