Sydney uploaded sweet images from the wedding Sunday and Monday on Instagram, and she noted how she's proud to be Mrs. Warner now.
"Mrs. Warner has a nice ring to it," Sydney wrote in her Instagram Stories.
Sydney tied the knot in a low-cut, form-fitted, mermaid-style lace gown with long sleeves. She later changed into a sexy second look for the reception, where she danced with Fred in a sparkly, sequin dress, one side of which was a mini-skirt.
Sydney revealed the "traditional ceremony" took place inside "a chapel that was flown over from France," according to E! News.
The newlyweds reportedly exchanged their own vows and had selected white roses, orchids and baby's breath for their flowers. Their guests also held onto sparklers while the bride and groom had their first dance as man and wife.
"It's been a long time coming and lots of planning," Sydney, who got engaged in May 2021, told E! News ahead of her big day.
"I'm super excited. You think, 'Oh, we still have such a long time.' But now that it's actually here, we're just so ready to see our family, and just be married already."
Sydney toldUs Weekly earlier this year that Fred slid into her DMs after The Bachelor's 24th season aired in early 2020.

"He actually sent me an emoji [because] he didn't think I was gonna respond and that's why he got really casual, but it was sweet," the Alabama native currently living in California shared with the magazine.
Sydney said she planned her wedding while Fred was deep into football season.
"Now we're in Playoffs, he's not involved," Sydney said at the time. "It's fine, he trusts me, we both have the same taste."
She added, "He is giving me the reins on that and it hasn't been as stressful as I would have thought it would be. It's been more fun. I'm just excited for it to all just come to an end and us just be there on that day."
Sydney called Fred and herself "sappy romantics," saying they had been looking forward to uniting their families and the "tearjerker stuff" that comes with Sydney walking down the aisle.
Peter eliminated Sydney at his season's sixth Rose Ceremony following a round of dates in Santiago, Chile.
"It sucks that he didn't get to see all of Sydney because there's so much. I came here with my heart and my mind so open and I was so willing to let those walls down," Sydney said in tears after Peter let her go.
"I want to feel like there's someone out there that can love me unconditionally, you know, be that rock for me and love me the way I want to love someone else."
