Aaron Carter, the brother of Backstreet Boys member Nick Carter has alleged that he was raped by his older sister.

"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," Aaron began. "I was 10 years old...." he wrote on Twitter.

"My sister raped me from the age of 10 to 13 years old when she wasn’t on her medications and I was absused [sic] not only sexually by her but by my first two back up dancers when I was 8 years old. And my brother absused [sic] me my whole life," he added. 

His outcry comes on the heels of his brother Nick filing a restraining order against him after he allegedly threatened him, his wife, his son and his in-laws.
