The British Telecom tower displays "it's a boy" to mark the birth of a baby boy for Catherine, Duchess of Cambridge and her husband Prince William, in London July 23, 2013. Already touted as one of the most famous babies in the world, the first child of Prince William and wife Kate faces a life in the spotlight like no previous royal, severely testing the couple's desire to give their offspring a "normal" life.
