AJ Buckley‘s family is growing — times two!

The SEAL Team star’s fiancée Abigail “Abby” Ochse is pregnant with twins, his rep confirms to PEOPLE exclusively.

The babies on the way, due around April, will join the couple’s daughterWillow Phoenix, 3½.

“Could not be more excited to welcome two more to the Buckley clan,” the actor tells PEOPLE, joking, “I guess we will be designing a diaper bag for twins now.”

News of the babies on the way came as quite the surprise for the couple, who struggled with infertility for over a year and were about to turn to in vitro fertilization when they learned they had conceived twins naturally.

“I was over the moon to find out we were pregnant, and then got the surprise of a lifetime when the doctor said, ‘There are two!’ ” adds Ochse. “We feel truly blessed and cannot wait for the addition of two new babies to our family. Buckley, party of five!”
