According to TMZ reports, a formal federal pornography investigation has been launched following a Wal-Mart employee’s efforts to sell photos of the 17 year old Jamie Lynn Spears breast feeding her baby girl, Maddie Briann Aldridge. Spears starred in the television series ‘Zoey 101’, and won a Nickelodeon Kids’ Choice Award for Favorite TV actress in 2006.

It is reported that since Jamie Lynn is a minor, selling or buying of such photos is a violation of federal laws which prohibit pornography. Peddling photos of a minor’s breast, even if not taken for sexual purposes, could land the seller and buyer in federal prison if the photos are marketed across state lines for the purpose of being lurid.

Law enforcement sources informed the Web site that federal and local authorities are looking for someone peddling twelve photos of Jamie Lynn, her older sister Britney Spears, her infant daughter Maddie and the baby’s father Casey Aldridge. One of the twelve pictures, which were dropped off at Wal-Mart in Louisiana to be developed, shows Spears exposing her entire left breast while breast feeding Maddie, who was born in June.

Reports say that the photos were taken on Aldridge’s digital camera. Aldridge had taken the camera card to his local Wal-Mart in Louisiana for copies. Authorities believe that someone at the Wal-Mart may have made extra copies, and then tried to sell them.
