Nicole Richie gained an estimated 35 pounds, which is a healthy, normal amount for expectant moms, while pregnant with son Sparrow James Midnight Madden. Richie admitted that while pregnant with her second child, she had late-night fast food cravings. Us Weekly reported that she would send boyfriend Joel Madden out to pick up In-N-Out Burger at 2 or 3 a.m.

While she may have given into pregnancy cravings, Nicole Richie traded in burgers for sushi soon after giving birth to Sparrow. The swap paid off, because shortly after her son was born in September, Richie was spotted looking slim and trim. While Richie hasn't spoken on how she shed the post-baby pounds so quickly, she credited her weight loss after having daughter Harlow in 2008 to breastfeeding and eating "bland" foods, like soup and fish. Us Weekly also notes that regular Pilates classes helped Richie slim down.

Voted FHM's Sexiest Woman in the World in 2007, Jessica Alba admitted in an interview with Cosmopolitan UK that during her pregnancy she's never felt less sexy and couldn't wait to lose all her baby weight. Jessica gained 25 pounds while pregnant and said she craved all food in general but told Fit Pregnancy that she had a sudden desire for citrus based foods like lemonade and oranges.

How did Jessica Alba manage to look so slim shortly after giving birth to her daughter Honor Marie? "I wore a girdle," the star confessed in a recent issue of Elle. "Eight weeks after my girlfriend had her baby, you could see her six-pack. She told me to put an elastic band around my waist -- any kind of band or girdle works."
The actress did, however, have to hit the gym to shape up to shoot Club Campari's annual calendar. "[The workouts] were horrible," she told the magazine.
It was reported in People that Jessica shed the baby weight on celebrity trainer Ramona Braganza's 321 Baby Bulge Be Gone plan. On it, Jessica opted for a low-fat, low-carb diet and worked out with her trainer six days a week.

You'd think there would be no surprises after having four kids, but supermodel Heidi Klum is still amazed at how her body changes during pregnancy. "The last month is unbelievable, how rapidly your stomach goes. It's huge," Klum told Page Six magazine. "The thighs, the butt -- everything explodes in the end." Klum told People she continued eating a clean diet that was light on carbs throughout her pregnancy.

Klum has reportedly been eating sensibly and working out in order to get back into shape. "I wouldn't say I'm back in shape yet. Everything changes when you get older. It was different when I was 31 with the first one and now being 36 with the fourth one." Klum famously walked the runway for the Victoria's Secret fashion show less than two months after having son Henry in 2005, and just hit the catwalk again -- only six weeks after giving birth to new daughter, Lou.

During her pregnancy with twins Dolly and Charlie, Rebecca Romijn told Page Six Magazine, "I can't move anymore...I'm a beached whale!" According to her husband, Jerry O'Connell, the supermodel and "Ugly Betty" star reportedly craved "a lot of ice cream."

Carrying twins is no small task, though Jennifer Lopez, our favorite Bronx-born songstress managed to do it in style -- even after reportedly gaining over 40 pounds.

It was widely reported that Lopez began construction on a gym for her New York home before the babies were even born. After she got the okay from her doctor, the new mom began intense workouts with celeb trainer Gunnar Peterson that included cardio and strength-training using her own body weight as resistance. Jennifer also has been said to have avoided red meat and eaten four mini-meals a day that consisted of fruit, raw vegetables and lean protein. Another slimming secret: Ordering from Fresh Mommy, an all-natural food-delivery program for expectant or new moms.

Last week, I tuned into the Victoria's Secret fashion show on television. Wow! What fun they have with bras and panties! And watching the models strut up and down the runway with their enormous angel wings and teeny underthings made me want to do some crunches at ten o'clock that night.
