This was not SJP's finest fashion moment. (Charles Eshelman/FilmMagic)Sarah Jessica Parker has become such a fashion icon that she's pulled off looks that most of us wouldn't dare try. Would you ever don a tutu on the streets of NYC?! SJP, on the other hand, made that and other ensembles work both onscreen in the stylish "Sex and the City," and offscreen at glitzy red carpet galas. So on the rare occasion that even she can't make a look successful, I have to scratch my head and wonder from behind my laptop, just as Carrie would ... Can anyone really make a completely dull and shapeless ensemble work?

The answer, if I'm judging by Parker's wardrobe, is definitely no. The actress, 47, disappointed in a baggy navy blazer over a busy black-and-white dress with way too many fabrics going on as she attended the NYC launch of the high-fashion brand Maison Martin Margiela's collection for chain retailer H&M on Tuesday. The unfortunate dress completely swallowed her petite

Klum lets her shirt do the talking while out with her bodyguard and kids. (PacificCoastNews.com)If Seal wasn't already bent out of shape over his ex-wife's relationship with the family bodyguard, now he will be. Heidi Klum chose to wear long-sleeve T-shirt with very choice words during an outing to the Los Angeles County Museum of Art with her four children and bodyguard boyfriend Martin Kristin on Sunday: "When we have each other we have everything." And to really twist the knife, Klum, Kristin, and the kids were all holding hands, just like a family unit.

The 23-year-old star, who used to be all pigtails and cardigans in the "High School Musical" TV movies, showed some serious skin on the red carpet at the premiere of "The Carrie Diaries" at the New York Television Festival on Monday night. Her little black dress seemed to be missing the middle section. The long sleeve For Love & Lemons Moonlight mini, which retails for $189, boasted cutouts on either side that extended well into the back. In front, there was a see-through crocheted panel that ran from the neckline to her waist.

The 56-year-old actress turned heads on the red carpet at the Princess Grace Foundation Awards gala in Manhattan on Monday night. Davis wore a shimmery gold gown that exposed one shoulder and hugged her curves for the posh affair. Her long, wavy auburn hair was down, and her flawless porcelain skin glowed.

Kate Upton is sexy in swimwear. (Steven Meisel/Vogue)Kate Upton's already reached the height of success for swimsuit modeling, gracing the cover of this year's Sports Illustrated Swimsuit Issue. And she's determined that her next career move will be taking the rest of the fashion world by storm! In a new interview with Vogue, Upton reveals that she's quickly learning just what it will take to follow in the footsteps of the mega-successful supermodels who've gone before her. "Coming from a sports-fanatic family, I really didn't know a lot about the small fashion circles," Upton tells the fashion bible. "When I was able to accomplish [SI], I slowly started figuring things out — and when I have a goal, I do everything to accomplish it."

Make that almost anything. The rising star insists that one thing she refuses to do is become stick-thin like most other models.

Katy Perry is often more whimsical than stylish, but earlier this year the "Wide Awake" singer went glam in a sheer ivory design from Temperley London. Just five months later, one-time pop star Ashlee Simpson chose to make the same dress a hit! Perry's obviously a much more in-demand musician these days, but can she triumph over Simpson when it comes to fashion? It's time for us to decide ... who wore it best?!

Kristen Stewart (George Pimentel/Getty Images)Kristen Stewart's first live interview since she cheated on longtime boyfriend Robert Pattinson in July was awkward to say the least, and it only lasted about half as long as it was supposed to! The live webcast was advertised as a 30-minute event to promote Balenciaga's new Florabotanica perfume, but the chat was over after about 16 minutes. Fans submitted more than 5,000 questions for the 22-year-old "Twilight" star about subjects as varied as Pattinson, her favorite music, and her decision to do her first endorsement deal with the high-fashion brand. However, the interviewer stuck to a dozen or so questions that were strictly focused on the fragrance. Sorry, RPattz fans!

Alexi Lubomirski/AllureSigh. "The Hills" was such a prolific show that even two years after it ended, former star Lauren Conrad is still talking about it! Who knew that when we were watching LC and Heidi argue over the villainous Spencer, or one of Audrina's monosyllabic conversations with Justin Bobby, that we were actually watching TV history?! This time, 26-year-old Conrad is dishing about the show in a new interview with Allure magazine, explaining that her former "reality" show, which apparently staged many scenes and completely invented storylines (particularly in its later seasons), gets a bad rap. "I think the story they told wasn't a dishonest one," she asserts. "The way they did it sometimes was. [The cameras] aren't going to be there for everything. Sometimes two of their main characters will get into a fight, and that's important to the storyline. The [producers] need that reenacted. Their thing was always: It did happen. They're not making this up: you just didn't see it."
