They shared a vlog of their trip to the doctor for an ultrasound, where they found out they were expecting two babies – not one.

Their twins announcement comes just seven months after they shared the heartbreaking news that Lauren suffered a miscarriage.

In an emotional YouTube video shared on May 30, 2020, Arie and Lauren revealed that they learned they were expecting their second child but soon after found out she suffered a missed miscarriage, which is when an embryo has died but has not been physically miscarried, per People.

Arie called the experience a ‘roller coaster of emotions going from scared at first a little bit because it was so soon, then happy, then stress and worry for weeks on end, and then obviously today was the bad news.’ 

Arie placed second on season eight of The Bachelorette with Emily Maynard; he became The Bachelor for the show’s 22nd season.

During the season finale, he proposed to Becca Kufrin but later ended their engagement on TV and rekindled his romance with the show’s runner-up Lauren Burnham.

Arie and Lauren married on January 12, 2019 and welcomed their daughter Alessi Ren on May 29, 2019.
