Jamie Lynn Spears has been exposed in mommy mode.
A photo of the teen breastfeeding her baby has allegedly been stolen and has sparked a federal pornography investigation, reports TMZ.com.
The actress' baby daddy Casey Aldridge had taken several photos of the Spears clan including Britney, brother Brian, mom Lynne Spears, Jamie Lynn and her daughter Maddie. In one photo, Jamie Lynn's left breast is exposed while she's feeding Maddie. The digital camera's memory card was taken to a Wal-Mart for processing. Law enforcment believes that a man, who has tried selling the photos and has yet to be found, had made extra copies at the store.
At 17, Jamie Lynn is still a minor, so the selling or purchasing of that particular photos could be seen as a violation of federal laws prohibiting child pornography.
Yet another photo features Jamie Lynn in a negligee holding the baby.
Jamie Lynn Spears is best known for her role on Nickelodeon's "Zoey 101."
