Though the pair had planned on having a big wedding, due to coronavirus, the 36-year-old told the outlet that they "scaled it way back."
"It feels really good to just have our nearest and dearest with us to celebrate," she shared. "Sweet and simple!"
On Thursday, Oct. 15, Courtney posted a pic from the Montelucia Resort and Spa on Instagram of her preparing for her and Humberto's big day.
The reality star wrote in the caption, "Heading into our wedding weekend feeling as relaxed as can be."
Courtney was previously engaged to Bachelor Ben Flajnik, whom she competed for on the 2012 season of the reality show. They split up after nine months together.
"After meeting over a year ago, we have decided to end our romantic relationship," Ben and Courtney said in a joint statement. "The ups and downs weighed heavily on us both, and ultimately we started to grow apart because of the distance, time apart, and our need to focus on our respective careers."
Though she made quite a few enemies during her time spent on The Bachelor for breaking the rules (such as skinny dipping and getting hot and heavy with Ben in the ocean), she ultimately used the experience as a career stepping stone. She wrote the book I Didn't Come Here to Make Friends: Confessions of a Reality TV Villain in 2014.
Courtney didn't return to reality TV to find love. Instead, she and her now-husband connected last year over Instagram. They got engaged in December 2019.
"I can't wait to marry this man, with our son there," Courtney wrote on Instagram at the time, along with a photo of her and Humberto holding up an "I Love New York" baby onesie. "Easiest 'YES' I've ever said."
"There was just a level of comfort and connection that I've never felt before," Courtney told Us Weekly in 2019. "I never believed I that feeling of when you know, you know until I met him. Nor have I been with someone that I so clearly wanted to start a family with."
