When the devil crosses paths with pop music, Prada doesn’t usually come into the equation. But that and other unusual pairings take place in Fashion Rocks, a new magazine hitting stores Tuesday. The mag is the work of the creative team behind Vogue magazine, including Editor in Chief Anna Wintour the inspiration for Meryl Streep’s character in “The Devil Wears Prada.” Beyonc and Jamie Foxx are on the first cover and will be featured in the main story, a behind-the-scenes set visit of their upcoming movie, “Dreamgirls.” The issue also has in-depth features on Elton John and Justin Timberlake and a sneak peek at Courtney Love’s diaries. The annual magazine which appeared as a free supplement in Vogue in previous years is tied to “Fashion Rocks,” a September 7 event at Radio City Music Hall, which will feature musical performances by Christina Aguilera, Beyonc, Bon Jovi, Black Eyes Peas, Pussycat Dolls, Rihanna, Scissor Sisters and Kanye West. A two-hour special will air the following day on CBS. A special section of the magazine called “Model Fans” is devoted to models meeting their favorite musicians, like Brazilian bombshell Gisele Bndchen meeting tattooed soul rocker Ben Harper.
