Born in Pont-Audemer, France, Laetitia Casta spent her childhood in the lush countryside of Normandy. At age 15, she was approached by an agent of Paris' Madison Models while building sand castles on a beach in Corsica. After her father agreed to let the agency take some test photographs, Laetitia's wondrous natural beauty impressed the founder of Madison models as well as the director of the French magazine Elle. Modeling contracts ensued and in 1993 Laetitia signed on with Guess? Jeans for a very successful advertising campaign.

In 1996, Laetitia became one of the lead models of Victoria's Secret and from there was featured in the Sports Illustrated Swimsuit Edition for three consecutive years. She has appeared on over 100 covers of fashion magazines such as Cosmopolitan and Glamour, as well as doing commercials for the cosmetics company L'Oreal. Laetitia made her feature film debut in Astérix et Obélix contre César, the most expensive French film ever made and a smash hit in Europe. Her acting career gained momentum when she starred in the TV movie The Blue Bicycle, set in WWII France.

Laetitia currently owns a flat in London and enjoys painting, writing, rollerblading, going to the cinema, and dancing in her spare time.
Once invited a homeless man for dinner in her hotel while in London. Laetitia Casta was victim of an agression by a Parisian cab driver. The man lost his temper in a traffic jam, and started to verbally abuse her while she was on her phone. Scared by the attitude of the man she and her friend paid and left the cab. The cab driver continued to insult them and got out of his cab to spray them with mace gaz. Later the cab driver made up a story (that she was playing merry hell and screaming) to justify his agression when the police arrested him. The tabloids simply repeated his version keeping it that way as it was more juicy and scandalous than the truth. The man was condemned by the court a week later.
