Washington, July 4 Russian dignitaries are upset with Madonna over the use of foul language to promote an upcoming show in St. Petersburg.

The Material Girl addressed the Russian crowd by saying "It's f**king great" at the beginning of an online audio teaser for her 'Sticky and Sweet' concert in Palace Square, scheduled for August 2.

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

This is not the first time that Madonna's Palace Square show has come under fire.

Many city officials fear that the concert could offend the moral and religious sensibilities of the citizens of St. Petersburg.

Mikhail Piotrovsky, the head of the city's Heritage Museum, has asked Madonna not to swear during the show. (ANI)
