For one American sprinter, Olympic fame has become a mixed bag. Her post-Games euphoria was quickly tempered by an upcoming legal battle.

ABC News has reported that Tianna Madison, who won a gold medal as part of the American 4x100 meter relay team in London, is being sued by her parents for statements she made prior to the Olympics.

Robert and Jo Ann Madison are alleging that their daughter was untruthful when speaking about their mismanagement of her funds and their allowing a young man who had perviously molester her into their home. The lawsuit says that Tianna and her husband, John Bartoletta, repeatedly made false statements to the media.

"Throughout her childhood, and into adulthood, Robert Madison and Jo Ann Madison have provided Tianna Madison with a loving, supportive and generous environment that has enabled her to achieve success as a sprinter, including her obtaining a gold medal at the 2012 Olympic Games, as well as achieving success in other athletic endeavors," the lawsuit read

A representative for Tianna Madison said she would not be commenting on the lawsuit.

The Madisons' relationship with their daughter has been strained for some time. They held a pre-Olympic rally for her in July, but she did not attend.

Robert Madison and Jo Ann Madison are each seeking more than $25,000 in damages.
