Known affectionately as “getting knocked up” or “bun in the oven,” being preggers has never looked as good as it does right now.

The perfect complement to any outfit, a baby in the uterus has made flat bellies a vice of the past. Our parents might recall the exact moment when Abraham Lincoln was assassinated or where they were when Versace got shot, but I can only hope that the news of Jamie Lynn Spears’ uh-oh created a similar ripple in the pond of pop culture. Although there are many theories circulating about why Jamie Lynn did the dirty deed (including absurd accusations of parental negligence), I personally believe that she must have caught a glimpse of how good Katherine Heigl looked after her one-night stand with Seth Rogen.

Judd Apatow’s summer hit, “Knocked Up,” does a perfect job of highlighting some of the many physical benefits of unprotected sex. The glow, the fashionable belly cleave and the possibility of having Paul Rudd as a brother-in-law are all valid, if shallow, reasons for conception.

And then, along came “Juno.” Drawing in audiences with the tantalizing possibilities of seeing Michael Cera in yellow short-shorts, Juno takes pregnancy to another level of cool. For anybody who has ever wanted to own a hamburger phone, make small talk with Dwight Schrute and drink Sunny Delight, Juno is boss. I heard along the gossip grapevine that Jamie Lynn herself took her mom to see “Juno,” in an attempt to win back her love and log in some much needed mother-daughter bonding time. I can only assume that this gesture was a complete success.

Many readers might now be asking themselves how this miracle of fashion can be purchased. Unfortunately, this is one little bundle that cannot be bought. Instead, try some of these timeworn traditions:

The One-Night Stand: Commonly mistaken for a modern-day fairy tale, this romantic story is both tried and true. Girl meets boy. Girl and boy imbibe potent liquor. Girl and boy make raunchy moves on crowded dance floor. Girl and boy forget safe sex procedures. Impregnation. Ladies, this method is simple. A classy belly bump is almost guaranteed. Warning: Takes approximately three months for results to show.

The Relationship: Already in a hot and heavy relationship with a college prince? Not to worry, you still have a chance. Casually forget to take the precautions that gynecologists and mothers are always going on and on about. These may or may not include the following: birth control, condoms, diaphragms and, most importantly, abstinence.

Artificial Insemination: Want to cut a real man out of the picture altogether? Technology today has made pregnancy a one-woman process. Schedule an appointment with your doctor to discuss options.

It might be hard to find one who approves of your reasons for wanting a baby in the womb, but don’t let that get you down.

You are an independent woman. In circumstances like these, I always like to follow this mantra: What Would Beyonce Do?

The Pillow: OK, I lied. A faux belly can be bought, but only at the risk of possible embarrassment. For those who are too scared to take the plunge into true babyhood, stuffing a pillow under your T-shirt is the only option. Here are some difficulties you might encounter: Be prepared to hazard questions about the sudden bump experience (i.e., “Margot, what is up with that pillow under your T-shirt?” Appropriate response: “Doris, don’t be mad because this shirt makes my stomach look fabulous!”) Meeting another, real pregnant woman might result in violence (i.e. “Girl, why are you walking around like some ignorant fool?” Appropriate response: Run away).

Still not persuaded that pregnancy is in? Critics need only to check out the fierceness of modern maternity wear to understand that non-elastic waistbands really do make your ass look fat. So say goodbye to the days of big butts and hello to the latest and greatest of all fads.
