It was with great amusement that I read Rihanna's latest River Island clothing line was designed with her own "fat days" in mind. Hahahahahahaha! Only she (at a size 6) would consider a collection that includes hot pants and fishnets "fat day" wear. (Oh to be 20-something with a body like hers!) But it did get me thinking about how universal that feeling is. No matter what size you are, or what kind of shape you're in, some days you feel pretty and slim and others ... not so much.

You know what "fat days" are, I'm sure ... those days when you feel extra frumpy and unlovely and bloated, whether it's because it's that special time of the month, or you've missed the gym (like say for the last four months), or you just overdid it all weekend. Lately, I've been feeling that way more days than not. But there are ways to pull yourself out of a fat-day slump. Here are my tricks and tips.

Whoa! Have you seen this photo of Christina Aguilera's bangin' body in a sexy black outfit? Um, has she lost a ton of weight, or has she lost a ton of weight?!? Most people can't pull off wearing a bra as a top -- but Christina made it happen.

She shared the photo on Facebook, which was taken while she was shooting a music video with Alejandro Fernandez. And as a mom who has had her own ups and downs with weight over the years -- it's highly obvious what kind of reaction Christina was hoping to get out of people with this particular photo.

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!

We hear so much about celebrities willy-nilly going and getting plastic surgery without so much as a hard 10-second thought about it that I think we forget that surgery is always serious and always carries some risk. No doubt surgery is worlds away from the medieval days when it was painful and extremely dangerous, with people routinely dying on the table. But it's still surgery. It shouldn't ever be undertaken lightly. And plastic surgery often isn't medically necessary -- lots of times it's not even cosmetically necessary. Let's face it, nobody NEEDS bigger boobs or a thinner nose. Still, surgery is generally so safe today that people are shocked when something goes wrong. The family of a mother of two is considering suing the woman's plastic surgeon after her "mommy makeover" went horribly wrong.

It can't be easy to have two sisters who are constantly praised for their appearance, but Khloe Kardashian maintains a positive body image despite having to deal with so many people criticizing her for her weight.

She opened up about her struggle with bullying in a new interview with Cosmopolitan U.K., and it's pretty tough not to find her words empowering, eye opening, and refreshing -- especially considering how hard it must be to be torn apart in the media because of your body.

Khloe says, "I was quickly criticized for not being a cookie-cutter sister like Kourtney and Kim."

Throughout history, the world has looked up to America's First Ladies for a variety of reasons. Eleanor Roosevelt was the first to be outspoken, fighting for civil and women's rights. Jackie O had an impeccable sense of style and an unparalleled elegance. Who could forget Nancy Regan's "Just Say No" to drugs campaign. Well it seems Michelle Obama is an inspiration of a completely different sort.

Photos from the L.A. set of the Captain America sequel have people FREAKING about Scarlett Johansson. They're lamenting left and right that she's gotten so skinny! Where have her curves gone?! What's with the red hair? She's a "shadow of her former self!" OMG, no more boooooobs!

Really, people? Look, I get it. The woman had made a name for herself in Hollywood in part by being a neo-Marilyn Monroe. Her signature bombshell looks are beloved by men and coveted by women. So to see her suddenly looking so, err, linear as opposed to curvaceous is a bit of a shock. But we shouldn't be so shocked.

Can you die from a tattoo? A healthy 23-year-old woman in Milan, Italy, reportedly died after getting septic shock from a tattoo, according to her family. She had visited a parlor on Thursday, and by Friday she was feeling "shivery" and had "pins and needles" in her hands and feet. By Saturday morning, she had died.
