The 28-year-old Love And Other Drugs star said that while love is 'wonderful' it can be one of the toughest parts of life.
She told the Chicago Sun-Times, 'Most people want love and the journey sometimes is really rocky to find it. It's an exploration and an adventure always. It's also one of the most wonderful parts of being alive and one of the worst parts of being alive when it doesn't go well.
'The movie is about what it takes to let love in. Love is hard work and it's scary, and it's all totally worth it.'
