'Teen Mom' Star Amber Portwood's Naked Photos Leaked'Teen Mom' star Amber Portwood's personal drama has made headline after headline this year, and it seems she's not slowing down any time soon.

RadarOnline.com has exclusive photos of the 20-year-old posing in her birthday suit at her friend's house, displaying not only her naughty bits, but the large portrait of daughter Leah she had inked on her stomach last year.

According to a Radar source, Amber's decision to take the racy photos was a spontaneous one. "She just wanted to pose!" A friend of the reality star added, "Amber fancies herself an old-fashioned pin-up girl."

Portwood's photos seem hypocritical, particularly after slamming Kim Kardashian for her racy past. "Last time I checked, Kim Kardashian had a sex tape floating around on the Internet, and I'm pretty sure she made a lot of money off of it," Portwood told E! News after Kardashian told fans that teen moms were "not people you should idolize."
