Mamma mia! 2012 brought a serious Hollywood baby boom, which means, lots of adorable maternity style.

Help us wrap up the second day of voting in the StyleBistro Awards by picking which celebrity mom you thought dressed best during her pregnancy. And don't forget to return each day for more stylish categories! The winners will be announced on August 21st.

Kourtney Kardashian: Kourtney's second pregnancy didn't stop her from making serious sartorial statements! Billowy blouses, lace maxis, and bright-colored blazers all carried Kourt to full term. We also love that her heel height stayed tall, and sunglasses absolutely fab, too.

Reese Witherspoon
: Like the adorable southern sweetheart she is, Reese's maternity style was all about soft fabrics like cotton and linen, simple stripes, and peasant-y bib tops. She also stepped out on the red carpet in a beaded blue gown with an Angelina-esque slit—go girl!

Nicole Polizzi, aka Snooki: You can take the girl out of the Jersey Shore, but you can't take the Jersey Shore out of the girl. Ever since she announced she was preggo, Snooks has been showing off her baby bump in the same blinged-out minis, flamboyant animal prints, and insanely bold colors she wore to Karma way back when.

Gisele Bundchen: Gisele recently announced she's pregnant again, which means, we (hopefully) get to see more of the urban-chic clothing combos she rocked during her first pregnancy (right). With her tummy just starting to show, the supermodel has sported a lot of loose raglans and even a metallic tee.

Jessica Alba: Jessica is a total street-style star—pregnancy included. The expecting celeb's  signature girly colors, free-flowing fits, and enviable accessories (she seriously always has the best sunglasses, bags, and hats) secured her place as one of the cutest mommies ever.

Alessandra Ambrosio: Even though the supermodel has an incredible body, Alessandra stuck to oversized sweaters and lots of scarves throughout her pregnancy. Our personal fave maternity moment was her blue and yellow printed dress (left) where she playfully showed off her tummy (and her amazing legs, too!).

Beyonce: Oh honey B! Even when pregnant, the gorgeous singer remained the radiant diva we all love. With a bright preggo glow, Beyonce never strayed from eye-catching sequins, sky-high heels, and uber-bright colors (especially blue!).

Jessica Simpson: JSimps didn't hide anything during her pregnancy. The star let her ever-growing belly show in body-hugging mini dresses, busy patterns, and an open leather jacket. Totally cute! 

Jennifer Garner: Jennifer clearly loves being mom. She's always photographed with her darling daughters, and just gave birth to her third child a few months ago. Her maternity style is casually comfortable with chunky knit cardigans as her outwear of choice. Like many other pregnant celebs, she also loves basic cotton tees and big bright scarves.

Hilary Duff: It's hard to believe that the star who once played Lizzie McGuire is now a mom, especially when she kept her wardrobe so young and fun throughout her pregnancy! Think floral wide-leg pants, fringed anything, and bright blazers like her yellow one above.

Sienna Miller: The British actress and model never left us wanting more from her wardrobe—from sleek and structured looks to flirty florals she knew how to keep her dress dynamic. We also adored her various accessories—whether it was a floppy hat, structured bowler bag, or on-trend circular sunglasses, she always looked styled to a T.

Vanessa Lachey: Vanessa has always been a total cutie. She's still pregnant, which means, she's still rocking fun flowy dresses, pretty prints, and trendy touches like her tie-dyed cropped jacket. We're already anticipating what sweet styles she'll showcase the next time she's expecting!

Now it's your turn—who do you think has the best maternity style? Answer below!
