Madonna modeling for H&M is amusing some people in the ad business. Legendary adman Jerry Della Femina, for example, thinks she may be a wee too old to represent for the youth market. “These kids trade in stars every two or three years, and many don’t know Madonna,” he told Page Six. “I could see her signing up with Loehmann’s, I can’t see her with H&M.” While Madge’s tireless mouthpiece Liz Rosenberg hoped Della Femina “takes a nice pill,” Loehmann’s got all excited at the cold-day-in-hell proposition. “We’d love to have Madonna,” said a spokesperson. “If we could afford her.” That’s so cute.
