Antonio Banderas refuses to spoil his children. The Hollywood actor says he and his wife Melanie Griffith make sure their kids know "the world is not Hollywood."He said: "I don't give them whatever they ask for. They have to earn it. I tell the kids the world is not Hollywood. I've taken them to Mexico and Argentina when I've been making movies there so they could see how kids in different countries live. They've seen the shanty towns."I don't want them to think that the world is just full of beautiful cars and houses and everything you want."Banderas is dad to Stella, 10, and stepfather to Griffith's two children Dakota, 17, and Alexander, 21. And it seems the "Shrek The Third" star's style of parenting is paying off with daughter Stella.He said: "My little baby, Stella, is a straight A-plus student. I don't know where she came from because I wasn't like that at all and neither was her mother."She plays and is sociable but when she gets home from school, she goes to her desk and does homework. I keep telling her, 'You don't have to study.' "
