Carly Waddell and Evan Bass are enjoying a tropical babymoon in Hawaii.
"Mommy and baby are in their Happy Place #babymoon @hyattmaui," Waddell captioned a picture of herself smiling in the ocean.
Bass shared a snapshot on his own account of himself and Waddell on the beach.
He jokingly thanked the Kardashians for "inventing" babymoons, where expectant parents take time to relax ahead of their baby's birth.
"Thank you to whichever Kardashian invented baby moons which are apparently a thing AND i AM HERE FOR IT @hyattmaui," the star wrote.
Waddell announced in August that she's expecting with Bass, whom she married in June.
She told fans the same month that she's pregnant with a baby girl, and posted a sonogram of her unborn daughter in October.
"Our daughter is already devious and uncooperative and standing on her head doing yoga when all we want to do is take pictures of her," the mom-to-be said.
"Seems pretty typical of a child made from @theebass and I!"
Waddell and Bass competed on "The Bachelor" Season 19 and "The Bachelorette" Season 12, respectively, before meeting and getting engaged on "Bachelor in Paradise" Season 3.
Bass is already dad to three sons from a previous relationship.
