Kelly Clarkson apparently has a competition going with Jessica Simpson. They’re each trying to take the crown for “Biggest Over-Sharing Celebrity.” And frankly, that’s not a title a lot of people want. Jessica is known for telling audiences all about her flatulence and splitting pants. And just about every other thing you’d never want to know about. But so far, she’s drawn the line at pee. And I respect her for it. But Kelly Clarkson just threw herself headfirst across that line, by telling Blender magazine that she pees in the shower. Thanks.

Here’s an interesting little fact about Kelly Clarkson for all you trivia fans out there: she’s a bit gross. In a new interview, the American Idol winner admits to both peeing in the shower and checking the tissue to see what color her snot is!

When Blender magazine quizzed Kelly on whether she feels that washing and urinating are best done separately, she told them: “Anybody who says they don’t [pee in the shower] is lying.”

And on the sticky subject of boogers she muses, “I mean, if you have a cold, you have to check, to see how sick you are.”

Call us old fashioned, but aren’t these the kind of things we’d rather not know about stars? You wouldn’t see Marilyn Monroe admitting to that stuff.

But according to Kelly, the oversharing is all part of her special charm.

“It’s not like people look at me as unattainable, some kind of star like that,” she told the April issue of the magazine. “People love the ‘real’ factor that’s involved, I think.”

Okay, I will grant Kelly that people don’t look at her as unattainable. She definitely strikes me as one of the celebrities I could definitely hang out with and have as a real friend. She’s accessible and real, and that’s good. But you can still have class. And it doesn’t even need to be 100% class… just like 80%. Just not talking about what you do in the shower that you should do on the toilet. Really, that’s all I ask. I will give her the mucus talk if she absolutely has to have it.

Celebitchy and I had a whole debate over just how gross it is that Kelly pees in the shower. I pointed out that pee is sterile and you can drink it, which she swears is untrue. And the internet was no help, since there are a lot of arguments either way. And Kelly has yet to say she does anything other than go in the shower, so compared to some of the stuff I just learned that people do with their urine (thanks Google), I guess that’s relatively benign.

The funny thing is, I had a really hard time writing this article without oversharing myself. Once someone starts talking bathroom stuff, it’s hard not to chime in with your own gross things or tales of woe. That’s why Kelly’s got to keep it classy. Once the cat’s out of the bag, everyone’s going to join in, and pretty soon we’ll know all about Brad Pitt and Clive Owen’s hygiene issues too.
