London, November 25 : The escort who claimed to have slept with the Italian Prime Minister Silvio Berlusconi has revealed her amazement at his stamina.

Patrizia D''Addario made the disclosures about Berlusconi’s private life in her kiss-and-tell book Gradisca, Presidente ("Take Your Pleasure, Prime Minister"), which recently hit the Italian shelves.

The 42-year-old provided details of the alleged night spent with the 73-year-old at his Rome mansion in November last year, reports the Telegraph.

Patrizia said she was stunned by the premier’s stamina, considering he has had prostate cancer.

She said: "He didn''t appear a bit tired, he kissed me again and again and again.”

Berlusconi has said he cannot recall Patrizia and has never paid for sexual relations with a woman but also acknowledged that he loves beautiful women and is "no saint". (ANI)
