She said: "I don't have any plans for a family yet. We're both a little young for that. "I can imagine that if I have children in the future I'll completely immerse myself in motherhood, because I tend to get obsessive about whatever I'm doing at any particular point." Diane says that despite their busy schedules, she and Joshua try their best to see each other as often as they can in order to make their relationship work, adding: "I've realised that if you want to make it happen enough, it will happen."

The "National Treasure" star was previously married for five years to French actor-director Guillaume Canet.
