The engaged couple — who have been battling the illness for over a year and were about to turn to IVF when they learned they had conceived twins naturally — revealed the pregnancy in October, with a rep confirming the news exclusively to PEOPLE.

“Couldn’t be more excited to welcome two more members to the Buckley family,” the actor joked to PEOPLE, “I guess we’re going to design a diaper bag for the twins now.”

“I was so excited when I found out I was pregnant, and then so surprised when the doctor said, ‘There’s two!’ ” Ochse added. “We feel truly blessed and can’t wait to add two more to our family. Buckley, party of five!”

In December, Buckley shared a video of their gender reveal to her Instagram account, showing the family of three opening a basket filled with blue balloons.

Although Willow broke down in tears at the commotion, her dad continued, opening the second basket himself. Once again, the blue balloons were released, marking a second boy.

Buckley and Ochse — an oncology nurse and lifestyle blogger — dated for two years before getting engaged on New Year’s Eve 2012 while vacationing in Hawaii. The couple welcomed Willow in January 2014.
