Some artist with his finger on the pulse of American taste has made a sculpture of Britney Spears, nude, giving birth (NVSFW)—a sculpture which “reveals the crowning of baby Sean’s head” and “also acknowledges the pop-diva’s pin-up past by showing Spears seductively posed on all fours atop a bearskin rug with back arched, pelvis thrust upward, as she clutches the bear’s ears…”
Free advice to any pregnant women out there who might take a statue of Ms. Spears as a role model: in the early stages of labor, if your baby is sunny-side up, this posture can make you more comfortable and maybe convince the kid to roll over. Once the baby is ready to come out, all-fours can be a good position to push from, but not with your pelvis in the air like a bitch in heat. Unless, of course, you are enjoying the contractions so much that you want to push the baby against the force of gravity.
P.S.: According to Wikipedia, the actual Spears baby was delivered by an elective C-section.
