The 'This Is 40' star - who gave birth to her first child Noah in September - has revealed her husband Brian Austin Green's 10-year-old son Kassius, from his previous relationship with actress Vanessa Marcil - is not particularly excited about their new arrival because he is too busy playing computer games.
