Madonna

Yesterday in New York City, Stella McCartney gathered a gaggle of beautiful models and invited all of her fabulous celebrity friends and fans to preview her latest 2014 Resort Collection. The event was held in the trendy West Village and included famous faces such as Madonna, Cameron Diaz, Anna Wintour, Kate Bosworth, Naomi Watts, Helena Christensen, Julianne Moore, Liv Tyler and her rocker dad Steven. Check out a few of the photos where you can see the clothing and the atmosphere by clicking on.

Beyoncé Knowles donned a black leather leotard to rock the stage at yesterday's Chime For Change benefit concert, The Sound of Change Live, at Twickenham Stadium in London. She was also joined by her husband, Jay-Z, during her live performance at the show, which included her new song, "Grown Woman." Before taking the stage, Beyoncé posed backstage for pictures with Salma Hayek, who cofounded the charity, as well as Gucci Creative Director Frida Giannini. She's headlining the concert, which promotes education, health, and justice for girls and women worldwide, and she was joined by many other famous faces to support the cause. Jennifer Lopez heated things up with her hit "Live It Up" and also linked up with Mary J. Blige for a special performance of The Beatles' song "Come Together." Blake Lively, who left her London hotel with husband Ryan Reynolds earlier today, Madonna, James Franco, and Jessica Chastain are a few of the other stars who have already taken their turn at the mic, while Florence Welch and John Legend have also taken the stage. Plenty of other A-listers have descended upon London for the charitable event — click through to see all the stars at The Sound of Change Live!

After her daring punk look at the Met Gala earlier this month, Madonna made another fashion statement at the Billboard Music Awards in Las Vegas on Sunday. She skipped the red carpet and made her racy debut on stage in a black fishnet dress and a fur bomber jacket. Madonna was honored with the top touring artist award, which was presented to her by Will.i.am. She shared her gratitude for her fans saying, "Thank you for supporting me for three decades. Without you I wouldn't be here."

Hold on to your (leather) hats: Madonna is being honored as the Top Touring Artist at next week's Billboard Music Awards in the States, thanks to the worldwide success of her recent MDNA tour.

The international superstar, clothing chameleon, and ultimate risk-taker has brought so much good to our lives — and single-handedly ushered in tons of trends since she hit the scene in the early '80s. From fingerless lace gloves to cone bras and stacks of rubber bracelets (the original arm party, in our opinion), Madonna has a long history of setting trends and paving the way for fashion freedom — and if her punk-inspired look from Monday's Met Gala is any indication, it doesn't look like she's stopping anytime soon. We're taking a look back at the many trends that Madonna set into motion — click through to see them all now.

This year's Met Gala attendees gave us good reason to think two outfits are better than one. And who can blame Ashley Greene for trading her dramatic Marchesa gown for something a little shorter come afterparty? Those iconic Met stairs (read: not ornate-dress friendly) alone could prompt an outfit change, but we think it gives this A-list set another chance to show off one more great look before night's end. Case in point: Allison Williams's surprising dark and sexy twofer, courtesy of Altuzarra. Or how about Madonna's Givenchy Haute Couture tartan and fishnets getup that turned into just fishnets all over? The beauty of seeing fashion's finest is actually seeing them at their finest, and that means outfit changes galore. Which stars were bona fide Met Gala quick-change artists?

When Beyoncé arrived on the red carpet at last night's Costume Institute Benefit at the Metropolitan Museum of Art, we thought the show was over: Queen Bey had arrived fashionably late to fashion's biggest night, and she stole the show in custom Givenchy. But just around the corner, Madonna — perhaps the original Queen of Pop — seemed ready to take back her throne. Moments after Beyoncé made her way atop the staircase, Madonna showed up in a look so punk, we thought she might have ransacked the museum's Punk: Chaos to Couture exhibition to get all the materials. (Which, now that we think about it, would have been quite fitting.)

Also in bespoke Givenchy, Madonna had all the workings of true punk royalty. For the details on her look and her afterparty attire, find them here in this gallery.

The Brits sure know how to rock it out punk style on the red carpet, which is perhaps why so many of them were in attendance at last night's 2013 Metropolitan Museum of Art Gala in New York City. Clad in every designer under the sun (more on who wore what British designers later), they were dressed to impress from head to toe with stunning accessories, gowns and shoes full of chains, studs and of course — fishnet. Take a look at these British beauties in my gallery here and leave a comment at the end letting me know who you think looked best.
