In Atlantic City on Friday, Beyonce took the stage in a skin-baring ensemble at Revel Beach's Ovation Hall for her first concert since 2011. Her debut performance is the first of four shows this Memorial Day Weekend.

By the looks of her bod, it's hard to believe that just five months has passed since the songstress, 30, gave birth to daughter Blue Ivy -- her first child with husband Jay-Z.

Lourdes Leon, Georgia May Jagger and Madonna (Iconix)Madonna has tapped a member of rock royalty to be the new face of her clothing line.

The 53-year-old music star has hired Mick Jagger's youngest daughter, model Georgia May Jagger, to appear in the marketing campaign for Material Girl, the junior clothes collection she collaborates on with her 15-year-old offspring Lourdes "Lola" Leon.

"To be handpicked by Madonna and Lola as the new face of Material Girl is truly amazing," Georgia, 20, said in a statement. "I've always admired Madonna's style and I'm thrilled to be working with them."

The Rock & Roll Hall of Famer was 62.

His death dashed the hopes of Bee Gees fans who'd hoped that a miracle was in store after the  singer emerged from a coma late last month. Prior to his regaining consciousness, his family had revealed that Gibb had been given only a 10 percent chance of surviving and seemed to be preparing the public for his imminent death. Despite the shock fans are now experiencing, family members surely feel grateful for the month they had with Gibb after his unexpected awakening.

Disco fans are feeling their mortality this weekend, as the death of one of the principal voices of the 15-times-platinum Saturday Night Fever soundtrack follows the passing of Donna Summer by a mere three days.

Robin Gibb, one-third of the Bee Gees, died Sunday after a long battle with cancer, his spokesperson has confirmed via a statement. Gibb was 62 years old.

"The family of Robin Gibb, of the Bee Gees, announce with great sadness that Robin passed away today following his long battle with cancer and intestinal surgery," reads the statement. "The family have asked that their privacy is respected at this very difficult time."

Two years ago, Gibb battled colon and liver cancer, but despite making what he called a "spectacular recovery," a secondary tumor recently developed, complicated by a case of pneumonia.

Gibb was born in Manchester, England, in 1949, along with twin brother Maurice. (Maurice died in 2003 of complications from a twisted intestine; eerily, Robin had surgery for the same medical issue in 2010.) Along with their older brother Barry, the brothers began harmonizing as a trio in Australia, where the family moved in
