Madonna has upset dignitaries in St. Petersburg, Russia by using foul language to promote an upcoming show in the city. The pop superstar proclaimed the Russian for "It's f--king great" at the beginning of an online audio teaser for her "Sticky and Sweet" concert in Palace Square on August 2.

Reports suggest members of the legislative assembly in St. Petersburg have addressed Governor Valentina Matvienko, with a proposal to sue Madonna for her comments.

It's not the first time Madonna's Palace Square show has come under fire - many city officials fear the concert could offend the moral and religious sensibilities of the citizens of St. Petersburg.

Mikhail Piotrovsky, the head of the city's Hermitage Museum, has urged the pop star not to swear during the show.
