Jenna, 30, posted three photos on Saturday, two of which showed off her noticeable baby bump on Instagram.

The third photo featured a pig and the following message: "I'm going to be a pig sister! May 2020."

Jenna captioned the slideshow, "Dear Baby, I hope you know that I already love you more than I could have imagined possible. I hope you chase all of your dreams, and I'll be there supporting you the whole way. I hope you get my spirit and sense of humor, and never stop laughing."

"I hope you get your daddy's thoughtfulness and work ethic, and never stop being curious," she continued.

"I hope you can ignore the negativity of the world, and always stand up for yourself. I hope you love Jesus with all your heart, and never forget how special you are. See you in a few months. Love, Mommy."

Jenna announced she's expecting her first child just six days after going Instagram official with Karl, whom she apparently met one year ago.

At the time, Jenna posted numerous pictures with the commercial real estate broker and explained on Instagram why she had kept their romance a secret for so long.

"I kept wanting to share this with you, but it's hard when there are people out there who have made it their goal to make sure I can't be happy. I had a fear about how social media can destroy what I love..but this is a huge part of my life, and I think it's about time I let you in all the way.️ Soo this is Karl," Jenna shared.

"I met him a year ago, and now I can't imagine life without him. He has shown me what it's like to be with a real man. With real morals. And with an unselfish and loving heart, and I'm never going back."

Jenna went on to share that she and Karl have traveled together and he's been the man behind the camera for most of her photos.

"But here you have it..this is the guy inspiring all my big smiles and dreams. The one who didn't care what show I was on, what drama was made up about me, or how many broken pieces of my heart he had to glue back together," Jenna continued.

"He is the best pig dad in the world. He is smart and funny...with an adorable southern charm. He makes me feel safe, and beautiful, and calm. For once my anxiety has started to fade. He is so special to me, and I feel lucky to be able to love him every day."

The Bachelor in Paradise alum concluded, "As always, I wanted to thank everyone who has supported me through the years. Those of you who laughed with me, cried with me, prayed for me, and genuinely cared for me...I appreciate every one of you. And I promise to continue to share more personal aspects of my life, because I want you to be a big part of it."

Later on, Jenna posted two additional photos of her pregnant body in bikinis at the beach.

Jenna first found fame when she competed on Arie Luyendyk Jr.'s season of The Bachelor in 2018.

Jenna then met and appeared to fall in love with Jordan Kimball, a quirky male model from Becca Kufrin's season of The Bachelorette, on Bachelor in Paradise's fifth season that summer.

Jenna and Jordan got engaged in Mexico during Bachelor in Paradise's finale, but Jordan broke up with her one day after the episode aired due to a series of leaked text messages appearing to show Jenna had been romantically involved with another man all summer long and dating Jordan just for money and fame.

Jenna allegedly bashed Jordan in the messages obtained by Reality Steve spoiler blogger Steve Carbone by saying she was better than Jordan and didn't even like him, and she also wrote some graphic sexual things to the unidentified man.

Jenna allegedly wrote to the North Carolina-based man: "I wanted to say sorry. Don't be mad at me or anything crazy. I know you're upset about this week's episodes but... this is all for my business. You know how much I need the money. Me and Jordan aren't together for real. I don't even like him let alone love him."

Jenna allegedly added, "I'm better than him and once I'm able to, I'll break it off for good and make up some story to make him look bad if it'll make you feel better. He means nothing to me and never has... All for work and networking. You're the only one I need in my life. The only guy who interests me. I need you to love me."

Jenna insisted the so-called leaked text messages were "fake" and "completely fabricated." She claimed she had never cheated on Jordan and was the victim of a "fraudulent attack" on her character.

Jenna subsequently revealed on Instagram she was taking legal action to bring the "terrible individuals" with "hateful efforts" to ruin her relationship with Jordan to justice.

Jordan, however, insisted to People at the time he knew Jenna very well and could tell she was definitely the person behind the text messages.

After reading the screenshots of the alleged text messages, Jordan said, "In my heart, I know it's her," and he said he felt sick to his stomach.

The Bachelor franchise host Chris Harrison told Entertainment Tonight in September 2018 if Jenna really sent those text messages to a guy, it was "a pretty terrible thing to do" because "Jordan is a very good guy."

"I know Jordan is very much in love with her, but then again... I don't know," Chris told ET. "All I can say is, 'God, I hope it's not true.' What a horrible mess and deceit."
