The 24-year-old actress is also apparently having a "super easy" pregnancy.
"I feel great," she says, [but] "it's kind of like a little alien has taken over your body. You just don't quite feel normal. But it's cool. It's been good."
Clearly Duff was in a sharing mood, as she also revealed the surprisingly intimate way she informed Comrie with the initial news that was pregnant.
"My husband makes this joke that I think I'm pregnant like 12 times a year. Every since we got married, he's like, you always think this blah, blah, blah," she joked. "So when it actually happened he was in the shower. I think sometimes when you imagine it you think you're going to do it in some cute way….I just ran in and he was in the shower and I just held up the test and I was like, 'oh my god.' And he was like 'AHHH!' He was soaking wet. We were just like a mess and started crying. It was really exciting."
