Is This Snooki and Jionni’s Official Engagement Photo?

Say cheese! Pregnant Nicole "Snooki" Polizzi happily posed with her fiancé, Jionni LaValle, for what could be considered an official engagement portrait on Wednesday. The parents-to-be were reportedly celebrating the end of filming for her "Jersey Shore" spin-off show with Jenni "JWoww" Farley. That could explain Snooki's choice of clothing and accessories in the Twitter pic: a fur-trimmed sweater, giant tiger-print bow, and matching (or rather, clashing) zebra-patterned earrings.

Ever since the pint-sized reality star, 24, announced she was pregnant, she hasn't been able to stop gushing about it. Snooki's Twitter timeline is full of adorable ramblings from the expectant mother, like what kind of music she wants to play for her bump and how her pregnancy has enhanced her cleavage. On Thursday, she posted photographic evidence of her growing chest, with the comment, "I got swagger with my pregnant self." When one fan tweeted back that her breasts had gotten "huge," she responded, "They won't stop growing. I'm scared."

Until the time comes for her little meatball to enter the world, Snooki has been getting her practice in — with a plastic doll. On March 22, she and JWoww were photographed carrying dolls swaddled in animal-print blankets around Jersey City, New Jersey, while

filming their new show. Snooki is due in the summer — around the same time she will be filming the sixth season of "Jersey Shore." If in fact the baby comes during her time at the shore house, her co-star Vinny Guadagnino revealed it will have its own spot in the group's Seaside Heights crib. "We're going to turn the Smush Room into a nursery," he told "The Insider" recently. "We're great role models for a kid. We'll make it work. And all these factors can only help the show."

We've all seen what goes on in that room, so let's hope Vinny was only kidding!
