"Saturday Night Live" alum and "Parks and Recreation" star Amy Poehler sported a baby bump before giving birth to Abel James Arnett on Aug. 6, 2010. It's the second child for Poehler and her husband, Will Arnett of "Arrested Development" fame. We're guessing the couple's babies are hilarious, as these kids have funny in the genes.

Demi Moore may not hold the star power she once did, but back in the day, her pregnancy was a big deal. Her nude pose on the cover of Vanity Fair in 1991, shot by legendary photographer Annie Liebowitz, shown here with the iconic photo, was extremely controversial. It showed that the pregnant female form can be just as beautiful, if not more, than a woman's standard slender shape.
Portman is a true A-list celeb, but not everyone is a fan. Former Arkansas governor and presidential candidate Mike Huckabee verbally attacked the starlet for choosing to have a child with fiancé Benjamin Millepied out of wedlock. Huckabee's comments created quite the controversy, but we're just glad that Portman and her son, who was born in June 2011, are both healthy and safe.

Two were adopted with former husband Tom Cruise, and she has two with current hubby, country music star and fellow Aussie, Keith Urban.

In the 1990s, Cindy Crawford was arguably the most celebrated model on the planet, and her fashion sense has never wavered, including when expecting. During both her pregnancies, she wore only the most fashionable maternity clothes and, not surprisingly, looked amazing.
