ROME — A self-described “escort” says Italian Premier Silvio Berlusconi personally invited her to two parties at his villas, where young, foreign women were plentiful.

Nadia Macri, 28, yesterday said she believed many of the mostly Brazilian and Russian women were minors.

She’s the latest woman to recount such evenings at the villas, adding fuel to a political crisis that has prompted the government to call for a vote of no confidence in two weeks.

Italian newspapers earlier published transcripts of the woman testifying that Berlusconi paid her for sexual favors.

Berlusconi attorney Niccolo Ghedini called Macri’s comments “devoid of any foundation.”
