SUGAR COATED: Hubert de Givenchy is testing his sweet tooth. The retired
couturier will design the traditional Christmas cake ­ or bûche de Noel —
to be offered by Paris’s Lenôtre catering and restaurant chain. Givenchy
will unveil his creation in a lunch in Paris in September.   Karl Lagerfeld
designed Lenôtre’s Christmas cake last year.
