Known as much for her age-defying looks as her music or upcoming Material Girl clothing line, Madonna and her beauty secrets are the focus of global speculation. How does she do it? One secret may be her young lover, Jesus Luz, whose home country of Brazil is a land steeped in beauty secrets. In fact, Brazilian news websites this week buzzed with speculation that Madonna was soon to consult Brazil’s world renowned Dr. Ivo Pitanguy, whose Rio de Janeiro clinic is an elite beauty haven, offering masterful surgery and top-of-the-line creams, ointments and serums (the line is available in the U.S. at Neiman Marcus and Bergdorf Goodman under the Beauty by Clinica Ivo Pitanguy brand). Perhaps creams, not diamonds, are a girl’s best friend.
