Alexandre Coste
Alexandre Éric Stéphane Coste (born August 24, 2003 in Paris) is the son of Albert II, Prince of Monaco, and his former lover, Nicole Coste, a native of Togo in west Africa.
He was born
Éric Alexandre Stéphane Tossoukpé. His mother changed her and his surname to
Coste and the order of his name to
Alexandre Éric Stéphane on 10 November 2004. He has two older half-brothers who live with their father, Nicole's ex-husband, in South America.
On 6 July 2005, six days before he was enthroned on 12 July, Albert officially confirmed, via his lawyer Thierry Lacoste, his paternity of Alexandre.
Alexandre is not in the line of succession as he is considered illegitimate. Monaco law specifies only "direct and legitimate" descendants can assume the throne. Under the current constitution of Monaco, Alexandre can only become legitimized by his father Albert marrying his mother Nicole. However, Albert could change the constitution and thus legitimize him through legislation. If he were legitimized, as the oldest son of Albert, Alexandre would become the heir apparent. He would also be put first in the line of succession and have the title of Hereditary Prince Alexandre. He would also be given the last name Grimaldi.
On 26 October 2005, Albert gave an interview to USA television personality Larry King in which he said his son would not be in line for the Monegasque throne nor would he ever bear the Grimaldi name. Alexandre will, however, have inheritance rights to the Grimaldi family fortune and his father's estate under French law.
Should Albert never marry or not have any legitimate issue, Alexandre remains an option if Albert would want to preclude the accession of his nephew, Andrea Casiraghi through his sister Caroline of Hanover. In the King interview, Albert said he would "review the situation" should it occur.
