Grace Kelly Born and raised Catholic, and attending Catholic schools, the The Rear Window actress famously gave up acting at the height of her career at age 26 to marry Prince Rainer of Monaco in 1956. The couple had strong ties to the Vatican and Pope Pius XII, as both countries are Catholic states. While Kelly died in a tragic auto accident when her children were still young, her devotion to the faith perhaps helped inspire the conversion of her son's wife, Princess Charlene, to Catholicism before her royal marriage in 2011.   Princess Charlene now finds "great spiritual balance" through the Church.
