Carly and Evan, whose June wedding in Mexico will air at some point during Bachelor in Paradise's upcoming fourth season, are expecting their first child together.
"SECRET IS OUT GUYS!!!! Evan and I are SO EXCITED to announce we are HAVING A BABY!!!" Carly wrote on Instagram. "What a beautiful, wonderful, wild year it has been and the adventure continues Feb 2018! (Also Evans face here is hilarious and wonderful)."
Carly was completely turned off by Evan's quirky charm and persistent dating advances at first, but she slowly fell under his spell. The lovebirds eventually got engaged on the season finale, which aired in September 2016.
"We are so happy to be expanding our family as we welcome Baby Bass in 2018," the couple told People in a statement.
The baby will join Evan's three sons from a previous relationship: Nathan, Liam and Ensley.
The Nashville, TN, residents called that June day "perfect," saying it was a "dream wedding."
"There was no better way to celebrate the start of our forever journey together. The setting, in a garden overlooking the ocean, created a stunning visual that I don't think anyone will forget," the couple previously told People.
"Evan's children delivered heartfelt and hysterical speeches that had everyone laughing and crying simultaneously. The love from Bachelor Nation has been overwhelming and we are so grateful to all who helped make this day amazing."
Carly told E! News in April that Evan is "very accepting" of her flaws and she appreciates how he is "nonjudgmental."
Meanwhile, Evan told the website at the time, "[I love] Carly's openness. I know exactly where she stands at all times about everything... [She has an] ability to process her emotions without a filter. I really love that she wears her heart on her sleeve and is able to just communicate without fear of anything."
Prior to falling in love in Paradise in2016, Carly competed for Chris Soules' heart on The Bachelor's nineteenth season. She also came close to getting engaged to Kirk DeWindt, who broke her heart on Bachelor inParadise 2.
Evan first appeared on The Bachelorette's twelfth season last year starring JoJo Fletcher.
