And as she told E! News in an exclusive interview, that plan might include a return to her music career—sooner than we expected—and even a possible move away from Hollywood.
That is, if her pursuit by paparazzi keeps up at the pace it's been going.
Despite a scary incident in which she was bombarded by shutterbugs while landing in Canada earlier this week, Duff said that for the most part, even during her pregnancy when she's an even more desired subject for their lens, she's managed to maintain a civil relationship with the paparazzi.
"I'm pretty pleasant to them now, and they are usually pretty kind to me," she said. "So hopefully there's a little bit more respect that goes into it. I'm not the first person in Hollywood to have a baby. Other people have found a way to deal with it and I think I will, too. If it gets too much, we pack up and move, I guess. Mike and I talk about that sometimes…"
So where would she move to?
"I don't know…Toronto?" she said, before changing her mind after being informed that the city now has its own fleet of paps. "Maybe Edmonton!"
"Sometimes it's a more pleasant situation where it's like, OK, I can deal with this," she continued on. "I'm mentally prepared that this is going to happen and I kind of assume that they are going to be there…And you just take a breath and you go because you have to, because what else are you going to do? And then some days it just sucks. Who wants to be photographed every single day?
"The thing is when everyone is creating a ruckus around you, everyone else that's standing around, it's embarrassing, because they're like who is that, what's going on over there? And you're just like, oh, I feel so helpless right now. And then the normal people start taking pictures of the paparazzi taking your picture. It's just a domino effect of situations that are happening."
Aggressive cameramen aside, Duff's life is pretty great right now—and that's largely down to her expectant bundle of joy.
"I think it's such a miracle. I feel so lucky that I've had an easy pregnancy and hope it stays that way. I think feeling the baby move and getting those little kicks…seeing it happen through your shirt or looking at your belly, it's like, wow, there's a life inside of me. It's a piece of my husband and me and it's really wild. It's really exciting to think about the future and also a little scary…but so exciting at the same time.
"We're giddy when we talk about it. We daydream about what our future is going to be like and what our child is going to look like and the little personality it's going to have. I think that's the craziest part."
Meanwhile, Duff also opened up about the possibility of returning to her music career in the coming years, and revealed that she's already testing the waters.
"I sing in my car so much and we always have music in the house," she said. "I think he really likes it. I just recently started taking vocal lessons again. I want to eventually make another record."
And eventually may be coming sooner than we thought.
"It just seems like a good time because I'm sitting idle a little bit. I feel very lucky to be able to not have to work during this pregnancy. I've been painting a lot and cooking and we've moved and I exercise all the time. And I've just been able to be me and be calm and really mellow during this time, and try to enjoy the peace and quiet.
"But I was also like I don't want to waste this time because I want to get my voice in shape. He kicks me."
Way to go, little guy! Sounds like it might've been just the kick this musical mama needed.
