The 32-year-old told British Cosmopolitan magazine: 'A great way to keep a romance alive is cook your partner's favourite meal.
'I make a really good lasagne, I don't know many men who don't like lasagne - I think making a mix tape is romantic, sweet and from the heart.'
Nicole, who has recently enjoyed a guest stint on the X factor, also shared her views on people who cheat.
She added: 'I can't comment on Tiger Woods or Ashley Cole – but I know cheating, if you're a man or a woman isn't good.
'The most important thing in a relationship is trust.'
