In his Instagram statement, Iglesias wrote: “It is with profound sadness that I respond to the accusations made by two people who previously worked for me.
He added: “I have never felt such malice, but I still have the strength to let people know the whole truth and defend my dignity against such a serious accusation.”
The singer also thanked the “so many dear people who have sent me messages of affection and loyalty”, adding: “I have found great comfort in them.”
According to by Spanish news site elDiario.es and US outlet Univision, which investigated the claims over three years, the women’s allegations are backed up by documentary evidence including photographs, phone records, text messages and medical reports.
Their reports cite other former employees who describe a threatening, highly stressful atmosphere for those working for Iglesias.
But an old friend of the singer, Jaime Peñafiel, labelled the accusations “absolute lies”, while another ally, journalist Miguel Ángel Pastor, said he had never heard “any suggestion that he might have committed this kind of act”.
Iglesias is one of the most successful Latin artists of all time, having sold more than 300 million records in a career spanning decades.
He is also the father of fellow music superstar Enrique Iglesias.
