Madonna has a new stylist these days — her daughter Lourdes. Just before Madge made her debut at MoMA for the Cinema Society screening of “W.E.” Sunday night, she had a Lourdes-ordered outfit change. Her daughter didn’t like the dress and cape the Material Mom had on, so her Madgesty did a last-minute switch into a Cavalli number. At the packed Piaget-sponsored after-party at Crown, M huddled in a booth with Steven Klein and longtime manager Guy Oseary and the film’s star Andrea Riseborough, and received well wishes from a crowd which included Chloe Sevigny, Jeremy Piven, Adrien Brody, Kim Cattrall, Parker Posey, Valentino and Giancarlo Giammetti, Barry Diller, Julian Schnabel, Patti Smith, Donna Karan and Glenda Bailey. The party raged on until after midnight, at which point a building resident came down to complain about the noise — but changed her tune upon seeing Madonna in the flesh from a distance.
