Who's the daddy? Cristiano Ronaldo cuddles his son at the launch of a film about himself in London... as football's royalty turns out in force

Real Madrid star Cristiano Ronaldo returned to England tonight and posed for the cameras with his five-year-old son, Cristiano Jnr (main pictures), on the red carpet at the glitzy West End premiere for his new documentary 'Ronaldo'. The Portuguese footballer allowed a film crew unprecedented access to his private and public life over 14 months, producing the documentary which will be shown around the world. It was made by James Gay-Rees - the producer of highly acclaimed sports documentary 'Senna', as well as the Amy Winehouse film 'Amy'.
