'Teen Mom' Amber Portwood in Nude Photo Scandal

Controversial ‘Teen Mom’ star Amber Portwood recently posed for a series of nude photos, Radaronline.com reports.

Portwood appears in a several photos released online that a friend took a few weeks ago.

The celebrity news site has several of the NSFW photos posted showing Portwood, now 20, in various states of undress, with the large tattoo of her daughter across her torso clearly visible.

"Amber fancies herself an old-fashioned pin-up girl," a source told RadarOnline.com. "She posed the way she thought a pin-up would."

The photos represent the latest controversy involving the reality star.

Portwood was charged with two counts of domestic battery, one count of neglect of a dependent, and one misdemeanor charge of domestic battery in late 2010 stemming from scenes on her “Teen Mom” show that show her attacking the father of her 2-year-old –daughter.

MTV is also involved with the case, saying at the time of her arrest that they were "cooperating with all parties and hope for a quick and fair resolution that allows everyone involved to move forward in a positive manner."

“Teen Mom” is a spin-off of “16 and Pregnant.” Both are MTV reality shows that follow the trials and tribulations of very young mothers.
