Madonna gig 'angers Russian museum'

Madonna has reportedly angered a Russian museum over her plans to stage a concert in one of the country's most famous locations.

According to the New York Post, the 'Material Girls' star is hoping to perform an outdoor gig in St. Petersburg's square, which houses the country's Hermitage Museum, in August.

Local officials are reported to have branded the proposal a "natural disaster", while museum director Dr Mikhail Piotrovski said he wanted "guarantees that there will be no blasphemy".

It is also thought that Piotrosvki will ask the singer to sign an agreement promising to keep her volume levels within specified limits.

The Hermitage Museum, founded in 1764, is one of the world's largest and oldest exhibition facilities, and houses some of Russia's most important works of art.
