DANGEROUSLY UNDERDRESSED!

BEYONCE KNOWLES has been criticised by a historical group who have deemed her scantily-clad dance on the tomb of a former US President as “patently inappropriate”.

The singer used “lascivious choreography” and her backing dancers were barely dressed, according to the president of the Grant Monument Association, Frank Scaturro.

Knowles performed on the steps of Ulysses S Grant’s tomb as part of the annual Macy’s Fourth of July celebrations in New York.

In his letter, which was sent to the Secretary of the Interior, Gale Norton and National Park Service director Fran Mainella, Scaturro wrote: “At that location, a certain decorum should have been observed from which popular entertainers are not exempt.”

Ulysses S Grant was the 18th president of the United States between 1869-77 and his tomb was erected as a national monument in 1897.

According to the BBC, Ulysses Grant Dietz, the late president’s great-great grandson said that he did not object to most live performances as long as the tomb was looked after. He added that the organisers could have been more thoughtful.

Dietz said: “If they’re doing a Fourth of July celebration and they’re doing it at a grave of a President, maybe they should look a little more closely at what performances are.”

NBC and Knowles were not available for comment and a National Park Service spokesperson did not wish to comment because he had not seen the letter.
