Minetti’s mother is an English dance instructor and her father an Italian businessman. Minetti worked for a while as a dancer on Colorado Cafe, a comedy-variety show on television. She then went on to train as a dental hygeinist.
In 2009 prime minister, Silvio Berlusconi, was attacked in Milan and required dental surgery where he met Minetti at San Raffaele Hospital. He invited her to become a politician and she was shortlisted for the upcoming elections leading to much criticism in the press. Berlusconi subsequently appointed her a regional councillor in Lombardy.
Shortly afterwards she introduced him to Ruby Rubacuori who was later to bring to light the so-called Caso Ruby scandal. During the investigation into the scandal it emerged Minetti owns 4 apartments in the Dimora Olgettina which are occupied by showgirls.
