But she could not resist adding her two cents worth, opining that gaffe-prone Berlusconi was "unsuited to govern Italy".
It was enough to enrage Berlusconi loyalists, including Carlo Giovanardi, an undersecretary in the Prime Minister's office. Demonstrating a level of skill with press soundbites on a par with the Queen of Pop's prowess in the director's chair, he said Madonna's opinion "counts for nothing, because Italians know that she's a multi-millionaire and that people are not going to be influenced by these rich and spoilt would-be lords".
Then realising, perhaps, that this might not be the best line of attack given the multi-billionaire premier, with assets of A5bn, was one of Italy's richest men, Mr Giovanardi changed tack, attacking her support of homosexual causes.
But as the Italian media continued to run with Madonna's comments, another PdL party politician, Daniela SantanchE, said the star had "insulted millions of Italians". Another PdL MP, former pop star Gabriella Carlucci, suggested that Madonna had employed a "communist press office".
The Prime Minister was not at hand to rebuff Madonna's remarks. He was knee-deep in meetings in Brussels, trying to convince senior EU officials that his government's drawn-out and chaotic attempts to impose a A45bn austerity package were about to finally bear fruit.
Sceptics, noted however, that Mr Berlusconi's trip enabled him to avoid an embarrassing interrogation by magistrates, who suspect he was blackmailed by the shady businessman Gianpaolo Tarantini, charged with procuring prostitutes for the premier's notorious parties in Sardinia and Rome.
But the consensus among most Italians was best represented by blogger Guia Soncini, who said that Madonna had merely stated the obvious - and probably managed to divert attention from her gaffe last week involving a hydrangea, when she took to YouTube to issue a bizarre mock apology to the flowers she confesses to loathe.
Perhaps she has more in common with Mr Berlusconi than she cares to think.
