The Evolution of Snooki's Growing Baby Bump

As Nicole Polizzi's due date approaches, let's take a look back at her second pregnancy -- via her burgeoning belly!

Shortly after Nicole Polizzi announced she was expecting baby number two, the "Snooki & JWOWW" star began to document her growing belly with a series of unforgettable selfies, snapshots and updates about her "babygirl." After all, this guidette wrote and perfected the unofficial guide for snapping the perfect shot of her expanding tummy. Side view, posture, the time of day and clothing choices all make a difference.

Now that Snooki's in the final stretch -- the "Jersey" gal is due to give birth to her mini-me meatball within the next month -- we're taking a look at the evolution of her ballooning bump courtesy of some official photographs, as well as slew from her personal collection:

When Nicole shared the exciting news that her brood was expanding in early April, the future family of four shared this sweet portrait. Lorenzo already looked ready to take on his new role, as evidenced by his bright "Big Brother" T-shirt.

The glammed-up future LaValles, with Nicole showing a bit of leg in a form-fitting frock, attended a wedding on Independence Day. Snooki also showcased how she went "hard" during the long holiday weekend: in her leopard jammies while clutching a baby bottle.

Even though the 4'9" mama said she was "HUGE," she hit the gym at NINE MONTHS -- in the blistering summer heat. Major kudos, Snooki!
