DiCaprio battles compulsions

Hollywood hunk Leonardo DiCaprio sympathises with his character Howard Hughes' obsessive compulsive disorder in the late tycoon's biopic The Aviator - because the Titanic star has been battling the condition throughout his life.

DiCaprio has admitted for the first time that he fights the urge to walk through doorways several times and is obsessed with stepping on every chewing gum stain he sees.
