The 65-year-old star also spoke of the couple's distress as they endured months of fertility treatment before it was finally successful.

Rod ' who has six other children from his previous relationships ' admitted he can be a strict father.

Now, the millionaire star hopes his kids will learn to stand on their own two feet and not take his success for granted.

He added: ' believe in tough love. I just wish one of them would get a job. It'd be nice to see another wage slip coming into the house."
