Mom-to-be Hilary Duff recently revealed that she's having a boy, and now she's opening up about baby names, morning sickness and more.

The singer/actress/author recently told E! News that she and hubby Mike Comrie have two names on deck for their new arrival. "We have one that's very traditional and one that's more unique, and when the baby comes out, we'll decide then," she said.

How unique? "It's not a fruit or a veggie," she quipped about her name selections. Chris Martin and Gwyneth Paltrow's daughter, Apple, can rest assured.

Duff is four-and-a-half-months pregnant, and has had a relatively smooth experience thus far. "I didn't have any sickness, it's just a strange feeling," she explained. "I think this trimester I got more energy. The first one I was like a slug."

The 24-year-old announced her pregnancy on her website in August. In a message to fans, she spoke of celebrating her one-year anniversary with Comrie, and divulged the exciting news. She wrote, “I can’t believe it has already been a year. Time really flies when you’re having fun! We also want to share the exciting news that baby makes three! We are extremely happy and ready to start this new chapter of our lives. Thanks to everyone for the continued love and support throughout the years!”

Duff recently released her second novel, 'Devoted.' The couple's first child is expected to arrive in the spring.
