According to a source, Galavis wed Osmariel Villalobos during a romantic ceremony in Miami, FL, Us Weekly reported.
"Only very close family and friends were invited" to the wedding, revealed the source, because "they both wanted to keep the wedding very, very secret."
Galavis, who starred onThe Bachelor's eighteenth season, reportedly began dating Villalobos in Summer 2016. In March 2017, sources told Us that Galavis was finalizing his plans to propose marriage, as he had already picked out an engagement ring.
"All their friends and family knew they were going to tie the knot eventually, but it was a surprise to a lot of their family members!" the source added.
The bride, 29, reportedly donned a beautiful, form-fitting Alejandro Fajardo gown with a lace bodice and short train. Villalobos shared a couple of photos of herself in the dress Sunday, August 6 on Instagram, one of which featured the 36-year-old groom smiling.
"THANKS to so many people who worked with me in SECRET to make this dream come true," Villalobos captioned one image in Spanish. "I'm going to start with my LOVED AND ADORED @alejandrofajardovnzla and all his team."
Villalobos wrote next to the photo of herself kissing Galavis, "I love you my husband," in Spanish as well.
The small ceremony was reportedly planned for the purpose of proper documentation, but the source said Galavis and his wife will enjoy an additional wedding in Venezuela.
"The couple could not be more in love," the source told Us.
It's unclear when exactly Galavis popped the question, but a source told the magazine in March, "She'll definitely say yes. They spend all their time together, and she gets along amazingly with his daughter [Camila]. All of Juan's family and friends love her. They have talked about marriage and both know it's what they want."
Sources raved at the time about how Galavis and Villalobos are "perfect" for and "crazy" about each another. They reportedly both enjoy sports and dancing, and it doesn't hurt that they have a "shared understanding and bond being from a similar culture."
The Bachelor franchise's only Latino man, a former professional soccer player, confirmed to Peoplehe was dating Villalobos in August of last year, revealing at the time the pair had only been romantically involved for a few months.

However, he was already smitten with the Venezuelan beauty queen, writing "I love you" as the caption to one of their Instagram photos together.
"I'm impressed by her. I'm amazed by the things she says and does," Galavis, who was born in the United States but raised in Venezuela, previously told People. "I'm happy to be with her... We're so much alike. She's like a female version of me -- the Juan Pablo that people know personally, not the TV one!"
Galavis and his ex Nikki Ferrell had a highly-publicized and criticized relationship following the finale of The Bachelor's eighteenth season in March 2014, which featured an anti-climactic ending in which Galavis told the Kansas City nurse, "I like you," and offered her nothing but his final rose after months of dating.
Many The Bachelor viewers disliked Galavis during his season for how he treated the women, and those negative opinions spilled onto Ferrell for choosing to be with him despite those alleged flaws.
"I knew I was never going to be the No. 1 priority, like, he has a daughter. But I mean, there's a difference between being the second priority and the seventh priority. We're just different people and... we just never saw eye to eye on [things]," Ferrell told The Bachelor host Chris Harrison in January 2015.
