The British star, who is preparing for his move from Real Madrid to the Los Angeles Galaxy, has signed a deal with Disney.
Beckham, 31, will play Prince Charming in a publicity campaign for Disneyland and Disney World.
The athlete told USA Today, "I’m the prince, and I’m sort of slaying the dragon, which is something I’ve never done before, obviously."
Beckham added that his new role will be a big deal for his three sons, saying, "It’s a big part of their lives."
The details of the agreement have not been revealed. Earlier this month, the former captain of Team England in the World Cup, took a deal with the Los Angeles team for $250 million US.
