Princess Leonor of Spain (L) and Princess Sofia of Spain peer into the UEFA EURO 2012 trophy as King Juan Carlos I of Spain receives players of Spain's victorious national football team at Zarzuela Palace on July 2, 2012 in Madrid, Spain.
Leonor was born in Madrid in 2005 to Crown Prince Felipe and his wife, Princess Letizia. Princess Leonor is currently second in the line of succession and is expected to become queen of Spain one day. However, due to Spain’s succession laws, if her parents ever have a son, Leonor’s crown would go to her brother instead. Talk about a sibling rivalry. So far, Leonor’s parents have given her only a little sister, Sofia, born in 2007.
