Whoa! After seeing Nicole Polizzi, a.k.a. Snooki, flaunt her bikini body by sharing pics of herself posing in two new sexy suits on Instagram -- it's probably time to retire the "I'm a mom and can't pull off looking hot in a swimsuit" excuse once and for all.

(I mean -- just look at her!)

She's dropped 42 pounds after having baby Lorenzo last August, and to look at her now, you'd never peg her as the mom of a 7-month-old.

I don't care whether you're a Snooki fan or not -- you gotta give her credit for working hard and getting her body back into fantastic shape, which is definitely not an easy task.

On behalf of moms everywhere, I'd like to go ahead and offer up a huge round of applause to Holly Madison for proudly showing off her post-baby belly. Yes, I said her post-baby belly. As in she still has one, as in her stomach is NOT magically flat a couple of weeks after having her baby girl, Rainbow Aurora.

OMG. Is there any bigger buzz kill than seeing a celeb mom on the cover of a magazine looking all svelte and perfect right after having a baby?

The answer is no. And even though she's a former Playboy model, Holly Madison knows that.

Sometimes we hang on a celebrity's every word. But we do it other times, too. Like with feeding our babies. People hear "breast is best" and some automatically feel this is a jab at formula feeding moms. It's not. We do what we have to do, and there's so much more to the important issue of promoting breastfeeding. Formula is "allowed" to be promoted by big companies with money to spend and breastfeeding moms don't feel personally attacked about that. So the same should go for breastfeeding.

Beyonce did a lot for breastfeeding because of her celebrity. If one woman tried nursing her baby because Beyonce did it, that's fabulous. But something else she did could really hurt new moms. Beyonce said she lost 57 pounds in three months because she ate lettuce every day.

We are finally getting a peek at Tom Brady and Gisele Bundchen’s two-month-old daughter, and no one is shocked that the child is beautiful. It’s almost like little Vivian Lake has a gorgeous mom and dad! Oh wait … she does.

Tom, Giselle, and three-year-old big brother Benjamin recently touched down in Hawaii, where they’re presumably spending some quality family time in the sun and sand. Giselle seems totally in love with her little girl -- she held her protectively in her arms as she exited the private jet, while dad grabbed the bags and Benjamin played nearby.

One of my favorite scenes in all the Housewives is the one where Real Housewives of Atlanta star Kim Zolciak is getting some in-home laser treatment for cellulite while eating a piece of pizza. It was at that moment that I was like, yes, I get her. She's prone to ridiculous weight loss treatments like said laser and some weird water-weight-eliminating full body wrap, and I dig her honesty about such laughable attempts at a healthy lifestyle. She's funny and frank.

But her latest attempt to shed some pounds is actually kind of normal. Kim sat down with Life & Style magazine and showed off her post-baby body after giving birth to son Kash just 15 months after popping out son K.J. Her secret to looking so good?

Megan Fox entered the motherhood club three months ago when she had her son Noah. She gained 23 pounds during her pregnancy and has lost 13 of them so far. And she's not working out. Many love to hate on Megan because she's gorgeous, says some odd things sometimes, and generally because she's gorgeous. Poor Megs. Fragile Megs. She's turned into one of my favorite new moms precisely because of that.

Megan says her body is too fragile for working out right now. So she's waiting. She's always been thin, and some people just drop those pregnancy pounds faster than others. And while she says she still wants to lose 10 more pounds, she sure looks amazing with them on here for the This Is 40 premiere. But who are we to say how much she should weigh? Provided she's a healthy weight, we should be happy for her. And happy for the fact that she's not rushing into working out -- something far too many of us, particularly celebrities, do after baby.

She may be a lot younger than me, but I've been able to relate to Hilary Duff so well ever since she welcomed her son, Luca, back in March. And it's not just because we're both moms or because we're both "boy" moms -- it's because she didn't shed all of her pregnancy weight as quickly as a lot of other celebrity moms do.

Nope, Hilary actually had to work hard for those pounds to come off just like most of us do, and I've been so impressed with her positive attitude about taking the weight off slowly and not stressing out too much over it.

And that's why when Hilary bragged on Twitter about being able to fit into her size 26 skinny jeans again (the equivalent of a size 2), I honestly wanted to stand up and cheer for her -- because I know just how good it feels to achieve your post-baby weight loss goal.

Losing 60 of the 70 pounds she gained during pregnancy hasn't been an easy feat, but Jessica Simpson's rockin' post-baby body is more than enough proof of what can be accomplished with a little hard work, patience, and dedication.

Since giving birth to her daughter, Maxwell, back in May, she's been counting her food points as part of the Weight Watchers plan (I'd count points too if I were being paid millions to do it), and she's been working out like a madwoman with her trainer, Harley Pasternak.

And even though she's a celebrity, which means she has certain luxuries that make it a whole heck of a lot easier for her to eat healthy and work out than most moms -- it's still hard not to be inspired by her slow and steady approach to shedding her post-baby pounds.
