Priscilla Presley posted a tribute to her late former husband, Elvis Presley, on Aug. 16, the 48th anniversary of his death.

Presley's attorney called the lawsuit "a sad and vicious attempt to falsely tarnish the reputation of an eighty-year-old woman."

Brigitte Kruse and Kevin Fialko filed the lawsuit Monday in Los Angeles Superior Court. Among many other allegations, they say Presley used them to financially exploit her name, image and likeness, hiding the fact that she had sold those rights decades earlier.
