Whoa! You guys aren't going to believe this story -- where do I begin? A mom in Duluth, Minnesota got the shock of her life earlier this week when she went to the emergency room with what she believed to be a strained muscle -- and found out she was actually about to give birth.

Mom of three Trish Staine was in the middle of a two-hour training session on Sunday for an upcoming half-marathon, and at the end of her run, she wound up with her back being all sore.

She waited to go to the hospital until Monday and figured when she got there, the doctors would probably tell her she'd pulled something. And you can only imagine her state of disbelief when she found out she was not only pregnant -- but that she was due to deliver the exact same day.

To say that Britney Spears has made a 180 since the days of her shaved head is an understatement. Britney is back, walking around on fire like the mistakes of her past never happened and she's boasting a slammin' bod to boot. We all know that Brit is a huge fan of yoga, which is how she tones up those killer legs. However, the "Toxic" singer and former X Factor judge has another major workout secret to keeping her rear in gear.

Her trainer, Tony Martinez, recently revealed one of Britney's biggest workout secrets to Perez Hilton. Calling Britney a "tremendous athlete," Martinez says that the key to Brit's great workout schedule is having fun.

Wait, you mean working out doesn't always have to be horrendous and dreadful? Of course not, people. In fact -- it should never be.

I don't usually tell people I'm afraid of losing weight. I know what they'd think. Another fatty making excuses about not getting her act together. But I'm not just another fatty. I'm a recovering bulimic.

I say recovering because, like alcoholism, there is no cure to bulimia. Yes, I've stopped throwing up, but the urge is always there. Eat a bowl of ice cream, think about going to the bathroom. Stand in front of the Xbox to work out and wonder if it wouldn't just be easier to stick my finger down my throat.

The truth is, I have never lost weight without throwing up.

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.

Sure, we all heard of Shakira before she joined The Voice as a judge. Heck, I loved her "Hips Don't Lie" back in the day and couldn't understand HOW she got her hips to do all that swiveling. But these days as a judge on the hit show, the Latina is making some serious waves and her name is absolutely everywhere. Personally, I can't get enough of her bubbly personality and, shoot, for a 36-year-old mother of one, the lady looks amazeballs. Seriously, how she lost all that baby weight for her gig on The Voice within five months of giving birth to her beautiful boy is BEYOND me!

Lucky for us, we have the inside scoop on Shakira's three biggest secrets for weight loss. Getting in shape never sounded so fun!

Guys, Britney Spears looks hot. Like really hot. Like that buzzed haircut is a thing of the past, she's been working out, and she put away her pajama shorts for a moment -- hot. The X Factor judge is on the June cover of Shape magazine rockin' a white bikini and showing off her newly toned physique. Yeah yeah, she's not quite in "Hit Me Baby One More Time" shape, but shoot -- momma looks fine.

Britney revealed her workout routine with Entertainment Tonight, saying that she's found staying in shape is MUCH harder as we age. Wanna hear how Brit keeps things in place in her 30s? Let's dish.

Now that wedding season is in full swing, advice for brides is unavoidable. Of course one of the most common topics -- apart from DIY decor and etiquette dos and don'ts -- is the pre-Big Day slimdown. How should brides be getting fit to walk down the aisle? Because, after all, as fitness and lifestyle expert Amanda Russell tells Us News & World Report, "The big moment of the whole day is ... they open those doors," and ... well, there's a reason the song is called "Here Comes the Bride." You know, no pressure or anything!

Okay, sure, you want to look your best. But now that my own Big Day has come and gone, I can confidently say I'm proud of how I maximized my fitness over the last six months to look and feel my best (and be four sizes smaller than when I started!) when "those doors" opened. Here, five significant steps I took to get fit to wed that could work for anyone, whether you're about to tie the knot or not ...

OMG, you guys. It's April. Like the end of April. And you know what that means? In a matter of a couple months, I'll be wearing shorts, sundresses, and (gulp) swimsuits -- which means it's about time to get my ass in gear and finally shed the extra layer of blah I've been carrying around since the holidays.

And that's why on Monday, I'm starting a 10-day Spring detox that will literally clean me out, refresh my spirit, and restore energy to my body so I can once again feel like I want to take over the world. (No, not literally, but you know what I mean.)
