The pop star has been dating the retired tennis ace and model for over a decade but his father has confessed he has never met the beauty.
Iglesias tells Britain's Daily Mirror, "I have to tell the truth, I have never met Anna. Yes, my wife, and my kids and his brothers have, but I have never met her, no, no, never."
But he approves of his son's choice of lover, adding, "Anna is very beautiful. They have good taste, my kids."
