Lots of new celebrity moms: Kim Kardishian just gave birth to Baby North, and Kate Middleton royal baby is already on everyone's curiosity list. Penelope Cruz had her second child, while Halle Berry is proudly showing off her baby bump. And now, Jessica Simpson, for the first time, came into public eye yesterday (July 25) since giving birth to her son, Ace Knute.

It seems motherhood suits our celebrities well and at the moment everyone seems to be in awe of it. Not only our celebrity moms enjoy these precious moments but they go to many miles to embrace the nine month occasion. Be it the fashionable maternity wardrobe or going nude in pregnancy, these moms do it all with an incredible spirit.

We at IBTimes salute their zeal and go back in times to have a look at the celebrity mom's who posed in a buff:

Demi Moore: Moore stripped down her belly back in 1991 for the cover of Vanity Fair. While posing for the magazine she mustn't have thought that her daring act would spark a trend.

Christina Agulira: The pop star never came out in open about her pregnancy but her secret came out when she showed her naked celebrity baby bump on the 2008 Marie Claire Magazine.

Monica Belluci: Belluci shed off her maternity wardrobe twice for the cover of Italian Vanity Fair. First time she did it to revolt against the county's laws against sperm donors.

Cindy Crawford: Seven month pregnant Cindy, posed nude for W Magazine.

Britney Spears: Britney went nude in pregnancy for two magazine covers, Harper Baazar and Q.

Jessica Simpson: We already told you that she has just given birth to baby boy. Before giving birth Jessica revealed it all on the Elle 2012 April issue.
