Moms-to-Be Who've Dared to Bare!

Following in Bellucci's footsteps, the former Wonderbra model gave us a peek of her belly in the February 2007 issue of Italian Vanity Fair.

The Italian actress showed off her bump for a worthy cause – to protest the country's laws against the use of donor sperm – on the August 2004 cover of Italian Vanity Fair.

"Women who have children late like me are always told how brave they are," says Bellucci. "But I don’t feel brave, I just feel very lucky."

Looking like a modern-day earth goddess, theJust Wright star showed off her growing belly swathed in a toga-like dress for Ebony's May 2010 issue. Son Julian Fuego, 1 month, arrivedright before the issue hit newsstands.

It's a double exposure! During her second pregnancy (with son Jayden James), the popstar debuted her naked bump (and new darker do) for the August 2006 cover ofHarper's Bazaar. Three months later, Spears and bump were cover stars again – this time for the British publication Q Magazine's 20th anniversary issue.

"I know that there are people out there who say that there is nothing sexy about being pregnant," says the first-time mom, who is expecting a baby boy on July 3. "[But] I feel empowered; I feel sexy.
