These days, being a celebrity pretty much automatically means you're going to eventually make your own perfume line. OK, not exactly, but you get the idea, right? Everyone from Justin Bieber to Kim Kardashian are perfumistas these days. But there's one celeb who wants nothing to do with it, and that's American Idol champ turned mega country star Carrie Underwood.

In a recent interview with AOL's The Boot, Underwood said that she has no interest in expanding her brand into the perfume world. "I really don't know if I would do the whole fragrance thing," she said. "I don't want to smell like anybody else ... if people walked up to me smelling like me, it might weird me out."

LOL. Said like a well-spoken A-lister, for sure. But you know what? I totes share Carrie's sentiment. I HATE smelling someone who smells like me, too. I'm actually a little bit embarrassed to say this ... but it makes me mad!

Kristen in Balenciaga.Kristen Stewart is one smart lady. I'm sure she's been offered umpteen endorsement and/or spokes-model deals, but the Twilight star patiently waited for the right brand to come along, and boy did it pay off. Women's Wear Daily reported today that Kristen just signed on to be the new face of a Balenciaga fragrance due out in the fall. If ever there was a more suitable pair, I cannot think of one.

Kristen's been slowly gaining speed in the fashion world over the years (her W magazine cover was certainly a highlight) and this partnership with Balenciaga is a match made in style heaven. Effortlessly cool, modern, appropriately dark, and perfectly moody, Balenciaga and KStew have a lot in common.

She's not the first celebrity to give face to a fragrance, but she may be the best.

Axe commercial.Hey, ladies! Ever wished you could smell like an eager college freshman or a cab driver? Now's your chance. Soon, there will be an Axe body spray for women. Unilever, the company behind the scent and its ridiculous ads, says that they're launching a uni-sex spray called Anarchy that will be sure to titillate the boys just as much as the girls.

I don't know if it's all the Axe chemicals floating around their offices and making Axe execs think this is a good idea, but hate to break it to you fellas: No woman I know likes the overt, in-your-face smell of douche bag in a can. We don't like it on guys and we certainly won't like it for ourselves.

Ever wonder what Bella Swan smells like? Wonder you shall no more. The new fragrance from the Twilight Beauty collection, "Immortal Twilight," is supposed to smell like our lovely, lovely protagonist. A combination of citrus, wild freesia, chamomile, musk, and patchouli, wear this scent and I'm sure you'll be attracting skinny vampires with amazing hair in no time.

Breaking Dawn Part I comes out in ten days (ten days!), so between this perfume and the Twilight hairstyling tools, we'll be all set to celebrate in style.

That Justin Bieber says some of the darnedest things sometimes. Sure, he may be a cutie (if you're a pre-teen and into that too-long faux hawk look), but when it comes to being a beauty product salesman, not so much. The 17-year-old charmer visited The Tonight Show and spoke to Jay Leno about his fragrance, Someday. And what he said made him sound totally clueless.

"What I was thinking [when I made this perfume] is like, girls are gonna like something that a guy is gonna like. I modeled it off of something that I would like a girl to smell like. They're gonna wanna smell like what guys want them to smell like, right?"

Sorry Justin, no dice. If Bieber truly believes that women want to smell how men WANT them to smell, he's got another thing coming. Doesn't he know we have our own opinions?

I've been wearing the same perfume, Ralph by Ralph Lauren, for more than 10 years now. When I smell the familiar scent, it feels comfortable and my own -- you know? But that doesn't mean I'm not open to new fragrances if I found one that piqued my interest. One thing I am NOT open to, however: swallowable perfume.

A new product from Lucy McRae and Sheref Mansy called swallowable parfum is exactly what it sounds like. Still in the research stages, the small pill will enable the skin to emit a "genetically unique scent about who we are and how we perform our identities," according to the product's website.

Was that English? I'll spare you the rest of this perfumista's mumbo jumbo. Essentially, you swallow this magical perfume pill, a bunch of "interactions" happen inside the body, and then you instantly smell like "the best version of yourself."

Hell. No. If you're like me and think the pill itself sounds sketchy, just wait until you see the commercial:

Emma Watson has become an accomplished fashionista over the last few years, turning up on red carpets in designer gowns and starring in a series of Burberry ads.

But her latest commercial for Lancome's Tresor Midnight Rose perfume is raising eyebrows for all the wrong reasons.

Every cheesy cliche is employed throughout the 1:45 video (which was shot by famed fashion photographer Mario Testino) -- and cheesy cliches aren't exactly unusual for a perfume ad -- but the ending is so ridiculous that I may have gagged a little.

You just have to see it for yourself to believe it ...

Appearing now in September fashion magazines is this two-page advertisement for Katy Perry's new(ish) fragrance, 'Purr.'

How many ways do I hate this photo?

Let me tell you ...
