News, Ellen asked Hilary if she knew what she was having. The star responded, "I do, but I haven't told anyone yet. I wanted to tell you first." The host started quizzing the author of Devoted to try to get the news out of her that way. "Are you craving anything?...I don't have a clue. I'm just going to guess boy." Hilary confirmed the guess and responded, "It's a boy!  Good job.  I had feeling it was a boy the whole time." OK! EXCLUSIVE: HILLARY DUFF EAGER TO KNOW BABY'S SEX In a recent interview, Hilary told OK! she simply couldn't wait to find out the sex of her baby. “The countdown has begun. Every single day, I’m like, ‘oh my gosh, seven more days!’ I’m so not the person who could wait and have it be a surprise. I give them respect, but I don’t know how people do that. I need to be totally prepared. I think it’s going to help me feel even more connected to it, to know what it is." OK! NEWS: HILARY DUFF CALLS HER PREGNANCY CRAVINGS "FEROCIOUS" Considering she's four months along, it sounds like she's getting her home ready for the new addition. She told OK!, "We’re moving, and we put new floors in and everything, and we were going to just leave that room alone and focus on rooms we were going to use more, and then we found out I was pregnant,” she says. “I was like ‘let’s rework the closet.’ We put a great bathtub in there that will make it really easy to bathe a baby. We haven’t done any design stuff. We have to find out if we’re going to be a boy or a girl before we can come up with colors.” Looks like now she'll be able to easily come up with colors for the nursery. Baby blue, anyone? Congratulations, Hilary and Mike!
