Princess Charlene of Monaco was pretty in pink at the Red Cross Gala Ball today, one of the world's most famous (and pricey) balls. Joined by Prince Albert II, the royal pair follow in the footsteps of Princess Grace and Prince Rainier of Monaco when they attended the same star-studded gala in 1958. The annual event was founded in 1948 and is held at Monaco Sporting Club. Although this isn't Charlene and Albert's first time attending the ball together, it is the first time they've attended as husband and wife. See more photos of the prince and princess of Monaco now.
