Penelope Cruz has a secret pastime - she regularly hosts star-studded dominoes games at her Hollywood home. The Spanish star entertains pals Salma Hayek, Daya Fernandez, Demi Moore and Ashton Kutcher at games nights, where they all play Mexican Train Dominoes. And Cruz is the fiercest competitor of them all. Kutcher reveals, "I've never been called such foul things as when I've played those games with Penelope. Outside the game, she's the sweetest, kindest friend you could have, but inside it, she's a vicious warrior."
