"Follow @tinytolbert for my weekly bump updates! I'm finally into the 2nd trimester! Baby is 13 weeks old, giving me bloat and stealing my butt. #bumpdate #tinytolbert #pancakebutt," Jade captioned the photo, which also showed the brunette beauty with her hair down straight and barely any makeup.
Jade and Tanner announced the pregnancy in late January, right after they celebrated their three-year wedding anniversary.
"Baby #2 is adding to our crew!! We are overjoyed our bundle of love will be joining us in August! We've been dreaming of you for a while now, and you are already loved beyond imaginable, sweet baby," Jade captioned a series of photos of her happy family on a beach at sunset.
"We are grateful for you all and thank you for allowing us to share our life with you! We are so honored to become parents again and can't wait to give Emerson a sibling. Our hearts are full and overflowing."
Jade and Tanner revealed they were trying for another baby in April 2018 -- when their daughter Emerson Avery, who was born in August 2017, was eight months old -- because they wanted her to have a sibling close in age.
While the couple will probably be thrilled to have a boy or girl as long as the baby's healthy, Tanner has made it known he wants to have at least one boy and is willing to continue expanding their family until that happens.
Jade initially competed for Chris Soules' heart on The Bachelor's nineteenth season, while Tanner first appeared on Kaitlyn Bristowe's edition of The Bachelorette.
Jade and Tanner met on Bachelor in Paradise in Summer 2015 and got engaged during the show's finale in Mexico.
The pair later tied the knot in January 2016 for a televised special on ABC, and then they hashed out their issues when they appeared on Marriage Boot Camp: Reality Stars in late 2016.
