Moms-To-Be Beyonce, Hilary Duff, Jessica Simpson and Maggie Gyllenhaal Show Off Maternity Style!

With the news today that Maggie Gyllenhaal is pregnant, we got to thinking about all the beautiful starlets who are expecting this winter. These days, celebrity moms-to-be aren't afraid of showing off their baby bumps with form-fitting outfits both on the red carpet and off, and we love it!

Beyonce hosted a promotional screening for the DVD release of Live at Roseland: The Elements of 4 at the Paris Theater in NYC last week. At this point, Beyonce should launch a red carpet maternity line because that is the most glam dress for an expectant mom I've ever seen. The long-sleeved black dress is sleek and sophisticated, while the gold darts on the sides of her dress accenctuates her growing belly.

 Over Thanksgiving weekend, Hilary Duff visited a park with hubby Mike Comrie and her puppy, and she looked pretty darned happy. We love that she wore a simple black fitted tee that highlights rather than hides her stomach. And throwing on a green statement necklace adds a bit of glamour to a casual outfit.

Jessica Simpson covered her tummy a bit more with a scarf and an oversized cardigan, while running errands in New York, but still looked cute with a casual side-braid. And makeup-free Maggie Gyllenhaal roamed the streets of New York, wearing a casual striped tee and cardigan, with 5-year-old daughter Ramona yesterday just after confirming her pregnancy.

So which celeb mom-to-be do you think has the best maternity style??
