The 66-year-old singer - who became a father for the eighth time in February when wife Penny Lancaster gave birth to Aiden, their second son together - admits he can`t always instantly recall what his kids are called, while one of the younger members of his brood, five-year-old Alistair, struggles to accept that his dad is the same man he sees perform on stage.
Rod said: "I`m very proud of my kids. The funny thing is with the little one - so many of them I can`t remember their names now - um, Alistair. When I`m around Als I`m `dad` but when I`m on tour, if I`m away for a couple of nights, he calls me Rod Stewart."
Rod likes to be a hands-on father to his children - but admits he has to leave Penny to undertake feeding and changing Aiden through the night as he doesn`t have the energy.
He told Australia`s `60 Minutes` show: "As long as it`s during the day I`m OK, I can`t seem to do the night things anymore."
The `Maggie May` hitmaker has been married three times and dated a string of beauties including Alana Hamilton and Britt Ekland, but insists he has no idea why he has been such a hit with women.
Asked for the secret to his love life success, he said: "I`m embarrassed, I don`t know, I mean I`m not a standardly good-looking bloke, I don`t know what it is. I mean, I`m not Brad Pitt am I?
"I used to do alright even before I was in the music business, you know, probably a good chat-up line and I think I can be fairly charming and well-mannered when I want to."
