Haylie Duff may be in her second trimester of pregnancy, but she says she and fiance Matt Rosenberg have put their wedding plans on hold. Since discovering she was pregnant, the couple decided to concentrate on their soon-to-be daughter instead.

“We still talk about things we want to do, but it’s a big change with the baby coming,” Duff, who is 29, told People magazine. “We’re just trying to focus on one thing first and then we’ll do it.”

“It’s pretty cool to think our daughter is going to be at our wedding,” Rosenberg told reporters at the 4th Annual Santa’s Secret Workshop in West Hollywood on Saturday–indicating that yes, there will indeed be a wedding. It simply won’t take place until some time after the couple have officially become ‘mom and dad.’

Haylie Duff is a very lucky pregnant mom. Instead of pickles and ice cream, her pregnancy cravings have been mostly healthy ones.

“I drink a lot of green smoothies,” she says. “I think I’ve craved health food, which is weird, and then the occasional mac and cheese.”

Her workout routine makes Matt Rosenberg a bit uncomfortable, however.

“He’s like, ‘Don’t push yourself too hard.’ I’m like, ‘I got it! I’m fine.’ I’m just trying to move. Go on walks. I’m not trying to put too much pressure on myself either way,” Duff shares.

“I feel better when I’m active. I try to do something every day, even if it’s just a little walk or whatever, but there’s some days I don’t do anything!”

Haylie Duff says Matt is already in fatherhood mode.

“He’s in dad mode already,” Duff says. “He’s up at six in the morning doing chores around the house. I’m like, ‘Who is this person?’”

After weeks of feeling a bit under the weather–and always tired–during her first trimester, Haylie Duff is excited to be experiencing a renewed sense of energy.

“The majority of pictures he’s taken of me are me passed out during the middle of the day,” she says of Rosenberg. “But everyone talks about this burst of energy you get in the second trimester and it’s very true. I feel like I’m back at it.”

Haylie Duff is, of course, the sister of Hillary Duff. She is also the host of Girl’s Real Kitchen. She was a cast member of both 7th Heaven and Lizzie McGuire.

It will be interesting to learn if Haylie and Matt plan a lavish wedding–with their daughter at the center of it all–after they become parents. Maybe they’ll find that parenthood has just too many demands in those first few months, to even consider such a thing. How long do you suppose it might be before Haylie Duff and Matt Rosenberg tie the knot?
