After months of rumours, Tatiana Santo Domingo's appearance at a Madrid fashion awards in November confirmed the happy news that the heiress was indeed expecting her first child with Princess Caroline's son Andrea Casiraghi. The baby will be born early next year.
As Prince Albert and Princess Charlene currently have no children, the new arrival will be third-in-line to the throne. Tatiana and Andrea probably don't have their minds on the succession, however, they will be too busy enjoying this special period before becoming husband and wife in 2013. Princess Caroline announced their intentions to marry in July.
