"I could share [the news] with my wife, but other than that, I couldn’t share it with anybody,” he tells PEOPLE. "I was just so happy for her when she told me."
Thiessen, 35, who later announced her pregnancy, has not yet returned to the USA drama, when she does, “she’ll be swarmed with hugs," says DeKay, who plays Thiessen's husband.
"She’ll make a great mom," says DeKay, himself a father of two.
In July, Thiessen told PEOPLE that she and husband Brady Smith had just celebrated their four-year anniversary and that "my priorities have shifted."
"We're hoping to one day start a family," she said. "We're just trying to time it out with work. We're getting there. We're now on that level that we're thinking, we need to make an addition to this twosome of ours."
