Jenelle Evans nude pics: Kieffer Delp 'has more blackmail'

"Teen Mom 2" star Jenelle Evans has been in the spotlight for a series of personal troubles since her first appearance on "16 and Pregnant." She's been arrested multiple times, struggled with substance abuse issues, had highly publicized boyfriend trouble, and remains at odds with her family.

Most recently, Evans opted to get a breast augmentation -- though unlike some women in the spotlight, she made no attempt to keep her enhancements a secret, candidly sharing the news with her Twitter followers. What she didn't expect was for personal before-and-after photos of her naked body to hit the press.

Evans' ex-boyfriend, Kieffer Delp, has admitted to selling the photos to RadarOnline. Evans, who says she was unaware that the "before" photos were taken and that she was high on post-surgery painkillers when Delp took the "after" photos, says she has no legal recourse against Delp -- because he has the ability to further blackmail her.

"I have a good case but he has more blackmail on me so I can't," she tweeted when asked about pressing charges against Delp. "I'm very depressed but I'll eventually get over it. I just wish I knew who to trust these days."
