Pop heart-throb Enrique Iglesias' grandfather JULIO IGLESIAS SNR is to become a dad again, aged 90.

The retired gynaecologist, father of crooner JULIO IGLESIAS JNR, revealed his 43-year-old wife RONNA KNEIT is expecting their second child, only a year after giving birth to their first son JAMIE.

The pregnancy - which is believed to have occurred through artificial insemination - will mean the Hero hitmaker will become nephew to an uncle 31 years his junior, and his famous father will gain a new brother just weeks before his 63rd birthday.

An insider reveals, "It took Julio and Enrique some getting used to. They've traditionally been the family's ladykillers so they're quite amused."
