Nicole Kidman has planned her two-month-old daughter's marriage.
The 'Moulin Rouge!' star wants Sunday Rose, her first child with husband Keith Urban, to marry Russell Crowe's youngest son Tennyson, two.
Russell revealed: "Nicole had one look at my younger son Tennyson, and looked up at me and said, 'I'm a great believer in arranged marriages'. "I believe she made the connection between Sunday and Tennyson now - so Tennyson is already engaged!"
The 'Gladiator' star also revealed he approves of his "beautiful" future daughter-in-law, and the pair have already met.
He added: "Nicole and Keith brought Sunday Rose around on a Sunday, which I thought was appropriate. "She is a beautiful child with beautiful delicate features and it was fun when Nicole brought her around - it was nice."
Russell - who also has a four-year-old son Charles with wife Danielle Spencer - says fatherhood keeps getting better.
He claimed: "It's the most fantastic thing I've ever experienced and it continues to get more fun and more complex with every day."
