Leonardo DiCaprio became a huge Hollywood star thanks to his role in the Oscar-winning film Titanic, but that didn't stop him from making a rather embarrassing error on set.
The movie tells the story of a wealthy teen named Rose (played by Kate Winslet) who meets struggling artist Jack (DiCaprio) on board the ill-fated ship and soon falls in love.
In one scene, Jack sketches a nude picture of Rose after she asked him to "draw me like one of your French girls".
