Cooper shared a slideshow of photos that included two baby bump pictures and a snapshot of her pet pig with a sign that read, "I'm going to be a pig sister! May 2020."
"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," Cooper captioned the post.
"I hope you get my spirit and sense of humor, and never stop laughing. I hope you get your dad's thoughtfulness and work ethic, and never stop being curious. 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," she said. "Love, Mommy."
"Soo this is Karl. I met his 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," Cooper wrote.
"We have traveled the world together and up until now he has always been the man behind the camera ;) 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," she said.
Cooper competed in Arie Luyendyk, Jr.'s season of "The Bachelor" in 2018.
Cooper then went on to appear in "Bachelor in Paradise" Season 5 and ended the season engaged to Jordan Kimball, however the couple's engagement later ended amid allegations she had cheated on Jordan and faked the relationship.
