Russell Crowe has penned an emotional letter to his two sons.

The Australian actor, who is married to singer Danielle Spencer, praised three-year-old Charlie and one-year-old Tennyson for blessing his life. His special message will now be buried in a time capsule for 25 years.

Crowe wrote: "Our lives have been blessed by you. Whatever comes along, I will always love you with my whole being and my soul."

He added: "I know I will have brought you up to love your mother above all. My hope is that you find the things, people and love that bring you joy and. Every day of my life is better because I am a father."
