Best and Worst Dressed Baby Bumps of 2011

Rocking the LBD -- Tina Fey

The 30 Rock star looks effortlessly stylish in this body-hugging frock. But next time, Tina, add some jewelry or a colorful bag, please!

Stealthiest Bump: Miranda Kerr

Miranda's fringy, flirty black number barely hints that she's a mommy-to-be and could stop any swashbuckling pirate in his tracks.

Most Curvalicious: Mariah Carey

The pop diva's elegant off-the-shoulder black dress and dazzling baubles remind us that this songbird has style to spare.

Red-Carpet Strut: Jane Krakowski30 Rock's Jenna loves to steal the spotlight, but in real life the actress let her bump take center stage. Here, she smartly balances her glam blue dress with a pair of bohemian bangles.

Most Fearless Bump: Pink

Proving she's no stupid girl, Ms. Moore flaunts her bump in a flattering silky sheath. We also love her Yep, I look hot 'tude.

Sweetest Summery Look: Jessica Alba

Jessica makes this cheerful print look stylish, not like a tablecloth, with her simple 'do, dangly earrings, and cute rope belt.

Most Fashion-Conscious: Jessica Simpson

With a smart leather jacket and animal print scarf, this singer-turned-fashion mogul is one hot mama with an edge.

Most Impossibly Impeccable: Victoria Beckham

The former Spice Girl's sleek pony and pearl studs accentuate her graceful neckline, and we love the pockets in her comfy yet sophisticated black tent dress.

Best at Feeling the Love: Beyoncé Knowles

Since this superstar songstress announced her pregnancy last August, she's hit the town in some fabulous fashion. Here, her glittering earrings, elegant dress, and sexy sideswept hair make it clear why this dreamgirl's no single lady.

Lamest Use of Toddler Decoy: Toni Collette

Okay, Toni, we know you're not one for the Hollywood glare, but the thrift-shop-y shirt, sloppy scarf, and flip-flops don't do your beautiful bump justice.

Worst Red-Carpet Look: Natalie Portman

The poised Black Swan star rarely disappoints when it comes to fashion, but this shimmery gown flops. The pink's too cotton-candy; the flower too intense; and the matching purse and lips a little too bold for the slim, sophisticated star.

Most Muumuu-Like: Kate Hudson

This sack of a dress has a splash of modern art and looks like it offers maximum comfort for itchy belly time, but it would work better as a wall hanging.

Least Bump-Embracing: January Jones

We appreciate January's uncomplicated look, but we wish she would have taken a cue from Betty Draper's glam maternity style and ditched the jeans and T-shirts once in a while.

Frumpiest Frock: Jennifer Garner

The actress's usually polished Red Carpet style took a disappointing turn when she wore this shapeless red dress.

Amy Tara Koch, author of Bump it Up, offers her top tips for looking fabulous when you're expecting.

1. Choose clothing that makes you look longer and leaner.

2. Invest in neutrals--they go with everything.

3. Don't hesitate to wear black--it's slimming, even when you're pregnant.

4. Layer on accessories; think necklaces, because you won't gain weight in your neck.

5. Wear a belt to create an Empire waist or to highlight your bump.
