The 'Maggie May' singer was devastated when the New Zealand-born model left him in 1999 after nine years' of marriage and admits he had to get professional help, although had to change therapists.
Rod - who has two children, Renee, 20, and 18-year-old Liam, with Rachel - said: ''Although the first counsellor was a joke. She came on to me.''
Although he was hurt, the 'You Wear It Well' hitmaker - who has fathered eight children with four different women - knew it was what he deserved because he had treated women so badly in the past.
He told the Daily Mail newspaper: ''I knew it was my comeuppance. I'd broken all these hearts. It was my turn. But it bloody hurt.''
The 67-year-old rocker is now happily married to model Penny Lancaster - mother of his two youngest children, Alastair, six, and 19-month-old Aiden - and says they have regular date nights to keep the spark in their relationship.
He said: ''Penny's getting ready now. A chef is cooking us dinner, which we will have on our balcony, which opens off the bedroom. When we are done we will send him home and ... she'd kill me if she knew I was telling you this, but 'Tonight's The Night...' ''
