Happy Birthday to Princess Caroline of Monaco and Hanover, who turns 61 today! The eldest child of Prince Rainer III and the famous Princess Grace of Monaco, Princess Caroline is the sister of Prince Albert II, and has been heiress presumptive to the Monegasque Principality for multiple periods of her life. Married three times, Princess Caroline has four children, and is currently separated from her third husband, Prince Ernst August of Hanover.
