"To everyone asking if I'm drinking while pregnant/judging without knowing... the answer is no, I'm not," Lauren wrote. "Mind ya own beeswax."
Lauren seemed to be responding to replies on recent photos she shared from a trip she and Arie took to Amsterdam.
In one video Lauren posted on Instagram, a bartender was pouring a mixed drink into the couple's glasses at the bar. However, the bartender could easily have made a mocktail for the soon-to-be parents.
Lauren revealed last week she's 14 weeks pregnant by sharing a baby-bump photo. Lauren explained her fetus is the size of a lime and growing eyebrows and eyelashes.
Lauren also disclosed at the time she and Arie had picked out their wedding bands throughThe Bachelor franchise's famous jeweler, Neil Lane.
The couple previously told Us Weekly they will be announcing the sex of their baby around the time of their nuptials and their little boy or girl is due in June 2019.
Lauren, who is reportedly pursuing a career in real estate, and Arie purchased a home together in Phoenix, AZ, in April 2018, just one month after getting engaged onThe Bachelor: After the Final Rose special on ABC.
