Madonna

The 2013 Billboard Music Awards rolled into Las Vegas on Sunday night taking over the MGM Grand. Stars hit the Billboard red carpet and made appearances on stage, but the real fun went on behind the scenes and in the audience. Check out celebrities and performers mingling backstage and posing for photo ops in between winning awards and grabbing the microphone. Jennifer Lopez shared a kiss with boyfriend Casper Smart, while Selena Gomez flaunted her gold costume, plus Miley Cyrus, Ke$ha, Madonna, and more mingled backstage.

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, 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 Ray-Ban Wayfarers and 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.

The fun wasn't over for the Met Gala 2013 attendees in NYC last night as they flocked to the Standard Hotel following the ball for the official afterparty at the Boom Boom Room. Madonna stripped out of her bum-baring Met Gala outfit and changed into a fishnet body stocking and black lacy lingerie to mingle with guests like Katy Perry, Allison Williams, and Frank Ocean. She wasn't the only star who made a costume change — Amanda Seyfried took off her gown and changed into a baggy black t-shirt to hit the dance floor with Frank. Meanwhile, Miranda Kerr met up with January Jones, Jennifer Lawrence arrived with Marion Cotillard, Gerard Butler mingled with Karolina Kurkova, andNicole Richie connected with Kirsten Dunst, and Mary-Kate Olsen snuggled with boyfriend Olivier Sarkozy. Mary-Kate and Olivier weren't the only couple at the late-night bash, as Jennifer Morrison was spotted holding hands with her Once Upon a Time costar Sebastian Stan and Kate Bosworth hugged Michael Polish. If you missed out on all the excitement last night, be sure to check out our collection of all the red carpet fashion from the 2013 Met Gala to get caught up!

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? Find out right this way.

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.

Madonna was the last celebrity on the red carpet at last night's Met Gala in NYC, arriving later than even honorary cochair Beyoncé Knowles. She walked the red carpet with her boyfriend, Brahim Zaibat, who accessorized with two flags. Madonna had another lucky guy on her arm as she did interviews with Givenchy's Riccardo Tisci, the man behind her creative — and short — ensemble. Later, Madge stripped down to lingerie and a fishnet body stocking to attend the official Met Gala afterparty with Riccardo and Brahim. She capped off the wild night by holding court with Katy Perry, Frank Ocean, and a host of other fashion cool kids.
