Letizia Ortiz, wife of Spain's Crown Prince Felipe, celebrates with her family this Saturday her 40th birthday, after showing for eight years as Princess of Asturias an active commitment to helping children and young people.

Education, the fight against painful illnesses, scientific research, aid for entrepreneurs and support for the disabled are among the many other causes of the journalist who left her profession to marry the heir to the throne.

Even so, Princess Letizia has made it clear that her priorities are her family and supporting the institutional duties of her husband.

In June 2005 she gave her first address.

Since then, the princess has given 60 speeches, in which she has typically expressed her concerns and priorities.

Notable among her efforts to promote well-being, progress and equality among Spaniards has been her work dedicated to helping children and adolescents.

From her post as honorary president of the Spanish Anti-Cancer Association, Princess Letizia has constantly taken part in meetings and activities on behalf of cancer prevention and care for patients and their families.

Long past are the days of her professional career as a jounalist, which began with the daily La Nueva España and continued with the Madrid newspaper ABC and in the Agencia Efe, before joining U.S.-based Bloomberg Television.

In 1999 she became a CNN+ reporter, writer and anchor, and the following year began an intense four years with Television Española, during which time she was honored with the Larra Award for Journalism, and which concluded in November 2003 with the announcement of her engagement to Prince Felipe.
