Hollywood moms before and after baby

Don't hate on them because they're famous. And rich. Hate on them because they look so darn good so soon after having kids.

Most women couldn't pull off a Herve Leger bandage dress normally, let alone a mere 4 months after giving birth! Not only did she lose the weight after having son Benjamin in record time, but the Victoria's Secret Angel, 29, seen above, left, at 7-month-pregnant, didn't even pack on the pounds like regular folks. Gisele, it's okay to indulge in a hot fudge sundae when you're preggers -- it's the perfect excuse.

But the Brazilian bombshell isn't the only one defying the odds. Check out these other star mamas who made losing their post-baby weight look no sweat ...

Reality TV star Kendra Wilkinson seen above, left, at 7-months pregnant, may be stressing about losing the baby weight on her E! show, 'Kendra,' but the new mama was looking as fit as ever on March 16 -- just 3 months after welcoming son Hank Baskett IV on Dec. 11, 2009.

'Dreamgirls' star Jennifer Hudson showed off her bump at Michael Jackson's memorial service in Los Angeles in June. The Grammy Award-winning singer, who was 8-months pregnant at the time, gave birth to son David Daniel Otunga less than 2 months later on Aug. 10.

But Jennifer, who's engaged to pro-wrestler David Otunga, brought her trademark curves back at the Whitney Museum Gala on Oct. 19. In fact, these days the songstress is looking better than ever these days with her newly svelte frame.

'Top Chef' host Padma Lakshmi may have had a bun in the oven, but you'd never be able to tell by looking at her! The 39-year-old beauty, seen above, left in November, 2009, gave birth3 months after this photo was taken to daughter Krishna Thea Lakshmi. But in less than a month the TV personality was back to her slim self, leaving onlookers stunned.

How did she do it?! Actress Leelee Sobieski gave birth on Dec. 16, but is already as trim as ever at the screening of HBO's 'How to Make it in America' on Feb. 9. This is the first child for Sobieski, 26, and her fashion designer fiance, Adam Kimmel.

Heidi Klum's done it again! Just five weeks after giving birth to daughter Lou Samuel, the supermodel is back to her bangin' bod just in time to host the Victoria's Secret Fashion show on Nov. 19. While Klum claims she still has 20 lbs. to lose, she looked as fit as ever in a body-hugging leather dress she donned for the after party.

But this isn't the first time the German-born stunner has said 'auf weidersehen' to those pesky pounds ...

Klum set the precedent for model post-baby weight loss when she hit the 2005 Victoria’s Secret runway show (above, center) less than two months after giving birth to son Henry in Sept. 2005.

The 'Project Runway' host’s trainer, David Kirsch, told the Daily News in December 2008, that Klum lost the weight through intense cardio workouts, circuit training and a strict diet.

'How I Met Your Mother' star Alyson Hannigan, shown on left in January, gave birth to daughter Satyana Denisof on March 24, the actress' 35th birthday.

In true Hollywood form, the red haired beauty's body was back in no time! Hannigan fearlessly donned thigh-high boots and skimpy lingerie for an episode of "Mother" in which her character, Lily Aldrin, plays a stripper. Now that takes guts.

Model Alessandra Ambrosio showed off her killer body at the 2008 Victoria Secret Fashion Show in Miami Beach, Fla. - only three months after giving birth to daughter Anja. According to her personal trainer, Leandro Carvalho, Ambrosio "had to pay the price" for indulging in rich Brazilian food and ice cream during her pregnancy, working it off by sweating through Carvalho’s special Brazilian Buttlift workout – a combination of ballet, squats, lunges and capoeira – for two hours a day.

While she may not look it, British lingerie model Katie Price (aka Jordan) is actually a mother of three. Price and her now-estranged husband, pop singer Peter Andre, welcomed their first son, Junior Andre, on June 13, 2005. The buxom Brit also has a son Harvey, now 7, from a previous relationship. Price and Andre later had a daughter, Princess Tiaamii Crystal Esther Andre, in 2007.

On April 20, 2005, the model's larger-than-life chest actually made her baby bump look comparatively small, despite the fact that she was seven months pregnant at the time. But in the blink of an eye, Price was back in her trademark skimpy attire - albeit with a new hair hue - in October 2005, despite having given birth a mere four months earlier.

A-lister Nicole Kidman booted her baby bump in record time! A mere 10 days after delivering her daughter, Sunday Rose, on July 7, 2008, Kidman was snapped getting out of her car in Nashville with not even a hint that she'd ever been preggers. During her pregnancy, Kidman reportedly kept herself in tip top shape, doing weight training, yoga, power-walking, aerobic cycling, and even worked with a trainer five times a week.

Nicole was back to her slim self just in time to promote her movie, 'Australia' and looked phenomenal at the Glamour Women of the Year Awards on Nov. 10. (Above, l-r) A seven-months-pregnant Kidman poses for photographers at the CMAs on May 18, 2008.

New mommy Jessica Alba may look like she bounced back from baby in no time at all, but the sexy actress revealed the sneaky secret to her post-baby body success ... and it didn't include hours at the gym. 'I wore a girdle,' the 'Fantastic Four' star and wife of Cash Warren admitted in the March issue of Elle magazine.

Above, left, Alba, who looked radiant at six-months-pregnant on March 4, 2008, gave birth to daughter Honor Marie on June 7, 2008. Girdle or no girdle, the actress looked stunning five months after baby on Nov. 13.
