Black pumps will always be a classic, but right now, it's all about white pumps. For proof, just look down at the famous feet of some of our favorite stars, including Angelina Jolie, who just donned white pumps with a white peplum ensemble at the World War Z premiere in Berlin. Kate Hudson paired white Christian Louboutin pumps with a pink tee and black leather skirt in NYC, Jessica Alba styled her floral trousers with white patent pumps, while Blake Lively glammed it up in a tweed pair by Bottega Veneta. If the thought of styling white pumps sounds a little scary to you, then see how these celebs styled theirs with an array of gowns, minidresses, shorts, and suits. See every head-turning look — and tips on how to incorporate white pumps into your own style — inside the slideshow. Hopefully they'll inspire you to snag a pair too.

Blake Lively stuck close by her husband, Ryan Reynolds, at Saturday's star-studded Chime For Change: The Sound of Change Live benefit concert in London. Their side-stage cuddle was the first time they've been photographed together at an event since they tied the knot last September. Blake and Ryan may have been reminiscing on their wedding day as they watched their pal Florence Welch perform during the concert since she also sang at the couple's South Carolina nuptials. They weren't the only pair to show their affection for one another over the course of the evening, though, since Beyoncé Knowles, who headlined the event, kissed Jay-Z in front of the crowd. When Blake wasn't on stage, she hung out with Zoe Saldana behind the scenes and met up with Salma Hayek's family in the stands — Blake even held onto Salma and Francois-Henri Pinault's daughter, Valentina!

Londoners got a major treat when singers like Beyoncé, Jennifer Lopez, Rita Ora, Mary J. Blige, and Ellie Goulding belted out their famous tunes for a good cause at The Sound of Change Live concert presented by Gucci as part of its Chime For Change campaign. The evening raised $4.3 million in ticket sales and will fund about 200 projects in 70 countries around the world — all in support of girls' and women's empowerment. Beyoncé, who performed a special 45-minute set as the show's headliner, looked flawless in a black sheer and leather Gucci ensemble. Other stars that didn't need to sing to look stunning were Zoe Saldana, Freida Pinto, Blake Lively, and Jada Pinkett Smith. Head inside for the full scoop on what everyone wore to this spectacular London affair, and enjoy seeing some of it tonight on a NBC special airing at 9 PM ET.

Zoe Saldana and Marco Perego got away to Capri over the weekend. The couple, who have reportedly been friends for a while, started dating recently after Zoe split from Bradley Cooper earlier this year. On Sunday, Zoe and Marco, who is an Italian artist, wandered the streets of Capri, stopping to slow dance in between embraces, and yesterday they took their PDA out in the sunshine. They kissed on a balcony before heading to a port, where they hopped on a boat for a ride around the island. The vacation comes during a break between projects for Zoe, whose Star Trek Into Darkness was released earlier this month, and her Out of the Furnace will hit theaters this Fall.

Marion Cotillard got dressed up in a Dior gown to join her costars Zoe Saldana, in Valentino, and Clive Owen and director Guillaume Canet on the Cannes red carpet for the premiere of their film Blood Ties this evening. It was a busy day for the crew since they got together for a photocall and press conference at the film festival this morning. Marion and her partner, Guillaume, who directed her in Blood Ties, were able to sneak in a kiss while celebrating the film together earlier today. Missing from the action was Mila Kunis, who is also in the film but currently stationed in London shooting Jupiter Ascending.

Marion has been making the rounds in France since last week, stepping out for the Chopard lunch on Friday and making a fashionable stop in Monaco to fulfill her duties as the face of Dior at the brand's cruise collection runway show on Saturday.

While the Cannes festivities upped the glamour quotient on this week's celebrity set, there's plenty more in the way of red carpet styling fodder from a crew we didn't see in the French Riviera. Olivia Wilde kicked off the week with the most elegant kind of Summer dressing in Morocco, while Zoe Saldana continued her very chic Star Trek tour stateside, and Coco Rocha showed off some high-wattage eventwear at the American Ballet Spring Gala. For a glimpse of those and more of this week's standouts, just start clicking.
