Prince Albert II and Princess Charlene got married on July 1, 2011. The pregnancy was announced in May 2014. Charlene was expected to give birth in October 2014, but she ended up giving birth in December 2014.

While Princess Gabriella Thérèse Marie and Prince Jacques Honoré Rainier are the royal couple's first children, Prince Albert II reportedly has other children (Alexandre Coste and Jazmin Grace Grimaldi) before getting married to Princess Charlene.

According to BBC News, Prince Albert II of Monaco admitted on July 6, 2005 through his lawyer Thierry Lacoste, that he is the father of Alexandre Coste.
