DeFer and her musician beau, 42, were quite surprised to find out they were expecting she told the mag.
“We weren’t planning on getting pregnant, so right now we’re just enjoying being pregnant,” she explained, noting that “right now” the couple has no plans to get married.
“We think it’s a boy. Well, the doctor is 95 percent sure it’s a boy,” she added. “The baby was really shy that day, he was sleeping.”
And Kaylee was correct. Congrats to the new family!
