Ok, so I know she's a celebrity, which pretty much automatically makes her look good in a bathing suit and all -- but these new photos of Kourtney Kardashian's bikini body are definitely something that should make us all stand up and cheer.

The pics are featured in US Weekly, and Kourt posed for them while on vacation with Scott Disick and her family in Greece. And she looks good. Damn good. It's highly obvious that she doesn't have one single ounce of baby weight left over since giving birth to Penelope, who is now 10 months old.

It's not every day we see a model -- especially a model in a bikini -- whose body reminds us of our best friend, sister, or our very own reflection in the mirror. That's glaringly apparent, given the extreme shock and stunned excitement that's unfolded in response to H&M's choice of Jennie Runk as their 2013 beachwear model. Everyone's jaws have fallen to the ground because ZOMG, the non-plus size brand tapped an attractive woman who's reportedly a size 12 to model swimsuits -- and not even just one-pieces. She's also in a bikini. Stop. The. Presses!

No, but seriously, after being criticized for always using "unhealthily thin" models, H&M decided to feature "a model who can illustrate this collection in an inspiring and clear way." What's more, they didn't even make a concerted effort to rave about Jennie's size. Because it doesn't matter. Good for them -- and great for us!

Whoa mama-to-be! Kim Kardashian's pregnant bikini body is plastered on the front of the new Us Weekly cover, and if I do say so myself -- she looks pretty darn amazing.

The photo was taken while she enjoyed a little fun in the sun with her family in Greece, and as you can plainly see -- the suit she's wearing really doesn't leave all that much up to the imagination.

It's about as stringy as string bikinis get, and the fact that she managed to pull it off while seven months pregnant should really be more than enough to shut up her haters once and for all.

Bethenny Frankel is going through one of the toughest periods in her life right now, but on the outside, things look better than ever. The reality mogul may be in the process of divorcing her husband Jason Hoppy and fighting for custody of their toddler daughter Bryn, but she was spotted at a Miami Beach hotel pool over the weekend looking absolutely flawless in a navy blue string bikini.

Sigh. I know they work out like crazy and have personal chefs and nannies and all kinds of other luxuries, but considering how amazing some celebrity moms look in a bikini, it's hard not to wonder if there's something in the water in La-La-land.

Honestly, are you even believing how ridiculously awesome Jessica Alba's bikini body is? This picture of her was taken as she relaxed in the sun in St. Bart's -- and her figure is nothing short of pure perfection.

I mean, she looks better after two babies than most of us do before we have kids. (So. Not. Fair.)

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.

To show off your baby bump in a bikini or not to show off your baby bump in a bikini, that is the question for beach-going pregnant women. And for most celebrities, putting their growing bellies out there for the world to see typically isn't an issue -- because they look just as great pregnant in a two-piece swimsuit as they do when they're not expecting.

Sigh. If only the rest of us were so lucky. Personally, I stopped sporting a bikini while pregnant once I got past the four-month mark. The mere thought of exposing my humongous baby bump on the beach made me cringe -- and I really didn't want to put other beach-goers through that kind of torture.

If I'd had Camila Alves' pregnancy figure, however, I'm sure I would've worn nothing but string bikinis for nine months straight.

I'm not sure exactly what kind of diet and lifestyle changes she's made in recent months, but after seeing a new photo of Britney Spears' bangin' bikini body, it's clear that she's taking very good care of her physique these days.

I mean, she really looks better than she ever has -- and even more toned and fit than she was in the shot at left, which was taken back in 2009.

And even though the hot pink suit she wore then was incredibly flattering, the new retro, striped two-piece she was spotted wearing at a friend's house in Malibu does even more for her buff bod. (And the new bling adorning her belly button is a nice touch too.)
