The Carter family saga gets more and more bizarre by the minute.... 

Just last week Aaron Carter alleged that his late sister, Leslie, raped him multiple times when he was 10 years old. Now he is accusing another family member of rape - this time his older brother, Nick Carter of the Backstreet Boys. He say his brother raped an elderly woman.

The allegation was made via a social media post:

"Hey [FBI] my brother raped Mildred and told me in confidence in his pick up truck she was 91 years old and my brother told me he covered her mouth so no one could hear her scream," the pop singer wrote.

"Put me on a polygraph machine please [FBI] my mother knows she was taking care of two elderly women who were on hospice Mildred and opal who my mother was keeping alive. [FBI] what are you gonna do about that!? NOTHING! ? I’m REPORTING A RAPE FROM NICK ON SN ELDERLY WOMEN WHO WAS DYING AND WAS 91 that he raped. Strap nick up to a polygraph machine and a really good one please."

Recently Nick Carter took a restraining order out against Aaron after he allegedly threatened to kill him and his wife. He then accused his sister Leslie Carter of molesting him when he was just a child:

“It runs in the family. I never wanted to tell anyone this. But I have too," Carter tweeted during the early morning hours. "My sister Leslie suffered from bipolar and took lithium to treat it. She never liked the way it made her feel and when she was off of it she did things that she never meant to do I truly believe that. I was 10 years old….”

“I have spent the last 15 years of my life going to therapy for abuse & rape, I’ve been through many different treatments, I have finally found the right treatment. I have had my ups and downs, I continue to work on my mental health and i will soon not have to take anything,” he continued, going on to deny that he has been diagnosed with any mental health disorders.
