Beyoncé Knowles's Fierce & Sexy Bump Style

When revealing on Wednesday that she is expecting twins with her husband Jay Z, Beyoncé paired the announcement with a stunning visual of herself cradling her sizeable belly. She wore a long veil while posing in front of a beautiful bevy of flowers.

Weeks before the Jan. 7, 2012, arrival of daughter Blue Ivy Carter, a very pregnant Beyoncé steps out in a black moto jacket, black button-down shirt, animal-print leggings and patent booties for some pre-holiday shopping in N.Y.C's Soho neighborhood Dec. 21.

The singer puts her growing belly on full display in a plunging-neck gown with gold accents at the Nov. 20 screening of her Live at Roseland: The Elements of 4 DVD at N.Y.C.'s Paris Theatre. "Thank God you can't really tell from the front, but when I turn to the side – oh baby!" she joked recently of her tummy.

From her bright crimson blazer and leopard-print scarf to her body-hugging jeans and platform booties, the first-time mom-to-be makes a fierce style statement while leaving an N.Y.C. office building Nov. 1.

Forget sweats! The RampB diva instead opts for a low-cut zip-up minidress by Carmen, sky-high pumps and rocker-chic sunglasses to run errands in N.Y.C. on Oct. 14.

Beyoncé shines in a Roberto Cavalli sequin blazer and tunic at the Sept. 21 launch of her new fragrance, Beyoncé Pulse, at the Dream Downtown Hotel in N.Y.C. "It's been great. I feel free. I feel very empowered," the singer recently told ET Canada of her pregnancy.

Work it! Joined by mom Tina Knowles, the radiant mom-to-be dons a low-cut black sequin jacket and matching pants from her own line paired with black-and-gold studded Ruthie Davis platform pumps to debut her House of Deréon Autumn/Winter 2011 collection at a Sept. 17 London Fashion Week event at Selfridges department store.

Hot mama! On Sept. 13, Knowles effortlessly switches from a Vera Wang leather vest and organza bubble skirt to a sequin knee-length dress for the Vera Wang and J.Crew shows during New York Fashion Week. Later that night, she attends the Tory Burch flagship store opening in a Michael Kors leather bodice gown.

From her bowler hat and Mama J by J Brand skinny jeans to her leopard-print Dolce amp Gabbana handbag, the radiant pop singer makes a diva-worthy pregnancy fashion statement at the Sept. 12 U.S. Open men's finals match.

Proving leather shorts can be a maternity staple, Knowles shows some skin in a low-cut burgundy top and matching bottoms while strolling with her guy in N.Y.C.'s Tribeca neighborhood Sept. 10.

After celebrating her birthday in Italy, the glowing star puts her budding baby bump on display in a white-hot bikini during a Sept. 6 trip to Croatia with her husband and sister, Solange.

The day before turning the big 3-0, Knowles rocks a tie-dye print Matthew Williamson halter dress and sky-high heels for a Sept. 3 date with her main man Jay-Z in Venice, Italy. "I always said I'd have a baby at 30," the singer shared recently.

"I have a surprise!" teased Beyoncé, cradling her belly in a tangerine Lanvin gown at the Aug. 28 MTV Video Music Awards. She later happily announced that she and husband Jay-Z are expecting their first child.

That same evening, the mom-to-be hits the stage to perform her new single, "Love on Top," in a '70s-inspired purple sequin blazer, white dress shirt and belly-accommodating black pants. "Tonight I want you to feel the love that's growing inside of me!" she yells to the crowd.
