Russell Crowe misses his children when he is away making movies. The 'A Good Year' actor has two sons, Charlie and baby Tennyson, with wife Danielle Spencer, and admits he feels lonely when he is away from them on set. Crowe, 42, said: "I've got two boys now and the whole priority of my existence begins with what they and my wife need. Whatever they need is where every day begins. When I'm away from them when I'm working I get lonely for their company."Crowe recently admitted fatherhood had made him realise how shallow the world of celebrity is and helped him put his priorities in perspective. He said: "The world of celebrity becomes this strange place to live in. But marriage and kids have made me less concerned with it."
