GAGA FOR HOLLY RUSSELL: Lady Gaga, who’s prone to provocative bodysuits and, as she says, “zoo animal” clothing, accepted the 2009 Billboard Magazine Rising Star Award at The Pierre in New York Friday in a gown so sheer and loosely flowing with a long train that there was little left to the imagination from the waist down, while the top was flamboyantly covered in feathers and hair. “It’s from an up-and-coming new London designer,” she said, later learned to be Holly Russell. Initially at the brunch-award ceremony, sponsored by Macy’s, Lady Gaga was choked up. “It’s just that my parents are here, and there’s my fabulous publicist with a hanky.” Regaining her composure, she explained the origins of her unique style, citing “the street, the local bar and leather jackets. But now my inspiration is my fans.” She did put in a word about her “hippie” mother’s influence. “I fondly remember mother sticking pipe cleaners on T-shirts, so I’m not all to blame.” A comparatively conservative Beyoncé Knowles accepted Billboard’s Woman of the Year award, wearing a striking and revealing Catherine Malandrino dress.
