Madonna turned 55 last week and she celebrated by throwing an insanely over-the-top French Revolution-themed bash in the South of France. The Queen of Pop went as the Queen of France, Marie Antoinette, naturally. Of course, Madonna's take on Marie Antoinette's fashion was slightly riskier than anything even the Dauphine herself would have dared to wear. And she let them--hundreds of party goers including Givenchy designer Riccardo Tisci, photographer Mert Alas, and all-grown-up daughter Lola--eat lots of cake (a custom confection cooked up by La Duree). And all of it was caught on Instagram. Take a look.

Naomi Campbell, Karolina Kurkova, Alek Wek, Angela Lindvall, Hilary Rhoda, Coco Rocha. And beyond gorgeous gowns. Need we say more? Of course we do! It's all in our review of Zac Posen Spring 2013.

It's Day 4 of NYFW and we're still kicking, though we have a few blisters now. It may have been our best day ever because we saw Naomi Campbell and David Beckham in the same 24 hour span. Are there two more gorgeous people on Earth? Aside from those pretty people (and some surprises, like Madonna's baby Lourdes Leon), we also spotted covetable clothes at DKNY, Orla Kiely, and Antonio Azzuolo, and morning margaritas at Lyn Devon.

The Jaggers are having a big week--Jade Jagger tied the knot this past weekend and today her half sister Georgia's latest ad campaign dropped. We'r

What young girl hasn't gone shopping in her mother's closet from time to time? There's just something really alluring about blazers with oversized s

We took a break from the front row this week to see what our faves were getting up to besides fashion shows.

After Taylor Momsen was dropped from IMG, it was no surprise to learn her reign as the face of Madonna and Lourdes' Material Girl line for Macy's was coming to an end. The homepage of the Material Girl website still says that they are "desperately seeking" a new Material Girl to be the face of the brand, and has been asking readers to write in who they think should be the next Material Girl since January 11. But the search is over. Material Girl has just announced on their twitter and then on their blog that they've selected Kelly Osbourne as the new face of Material Girl for 2011. "We’ve had a long time crush on Kelly and featured her as one of our “cool peeps” over the summer," the blog reads, "We are so thrilled." Apparently the crush is mutual. After being featured as one of Material Girl's "cool peeps" last summer, Kelly responded by writing, "to be thought of as an inspiration in that way is brilliant… I hope little girls look up to Lourdes because she doesn’t dress too grown up and she always looks so stylish," Grazia is reporting. Osbourne is a great (read: safer) choice to be the face of Material Girl.

Fashionistas are getting younger and younger these days. This past weekend, Sally Singer's T featured 13-year-old Chloë Grace Moretz, star of Kick-Ass and the forthcoming The Fields styled in a Wren tunic (Moretz wore it like a dress). She wore Chanel Resort to her last awards show. In Milan this past season Willow Smith made the rounds with mom Jada, sitting front row at Dolce & Gabbana, Ferragamo and Emporio Armani. And Emma Watson, a college sophomore, can do no wrong on the red carpet. Bloggers Tavi Gevinson and Jane Aldridge have proven that style doesn't necessarily come with age or fame. There are countless other stylish stars (movie and internet) who can't legally drink but dress better than me. Here are our top 10 mini trendsetters.

Watch out Lola Leon and Suri Cruise, nine-year-old Willow Smith is gunning for the title of most fashionable celebrity offspring. Sure, she doesn't have a clothing line like Lourdes (yet), but her new single, "Whip My Hair," sound pretty awesome, and this mini-Rihanna has got style for miles and works the red carpet like a seasoned pro. Up next for Will and Jada Smith's youngest? A stop in Milan to view the spring collections, of course. We hear she'll be front row at Ferragamo on Sunday with mom Jada.

Madonna's been pretty tight-lipped about W.E., the movie's she's currently directing and co-wrote. The plot has something to do with King Edward VIII's affair with American socialite Wallis Simpson (they later married), played by James D'Arcy and Abbie Cornish. And Lourdes Leone will be taking a break from blogging to make her acting debut in the film. It's Madonna's second time directing, and she told Interview that this film has a "bigger story" and will be "more layered and complicated" than Filth and Wisdom, her directorial debut. For her second attempt at directing, Madonna is pulling out the big guns. Some exclusive photos sent to us by a tipster show that she's getting some high profile high fashion help. Looks like famed fashion photog Steven Klein is giving her Madgesty some advice while on set in Brooklyn last week. Of course it's not the first time Madonna and Klein have worked together. The two paired up for an exhibition back in 2003, and he shot her for several editorials. Hopefully this bodes well for W.E. making a bigger splash than Filth and Wisdom.
