R. Kelly’s brother, Carey "Killa" Kelly, is back with new allegations against the controversial singer following a song in which Carey aired his grievances with R. Kelly.

Tasha K posted a lengthy chat with Carey Kelly to YouTube Monday.

In the interview, Carey accused the “Ignition” singer of sexually abusing their 14-year-old female cousin, reports Hot New Hip Hop. Carey was reluctant to go into detail about the allegation but said the incident caused “turmoil” within the family. The famed singer's brother also said he believes it is possible R. Kelly fathered the cousin's child.

“A lot of people didn’t believe it because of who he is, and that’s how he’s been able to sustain in this business as an artist and as a human being [without] being locked away,” Carey said. “It’s almost hard to believe that this icon, this superstar, would do things of that nature.”

Carey also addressed R. Kelly’s inappropriate relationship with the late Aaliyah.

“I picked it up when he was working on her album, and he started producing Age Ain’t Nothin' But a Number. I’m listening to the [lyrics], and I’m paying closer attention to how they’re vibing ... they’d be right next to each other, hugged up and different things of that nature,” Carey said. “That didn’t seem right with him being the age that he was, and her being the age that he was.”

Tasha K asked about abuse allegations from R. Kelly’s ex-wife, Andrea; Carey collaborated Andrea Kelly's claims, saying all of them are true. He accused his brother of not only hitting his ex-wife but consistently humiliating her by forcing her to crawl on the ground like a baby and to get permission before she used the bathroom.

R. Kelly had accused a family member of molesting him when he was a child. In his sit-down with Tasha K, Carey said the same family member molested him, as well, and argued being a survivor of abuse does not give one license to harm others.

“Robert has a control problem. And the only reason why he targets little girls, now that I’m older, I understand. He was molested. I was molested [too], but I didn’t turn out that way,” Carey said. “I became a protector of children. I didn’t want kids to go through what I went through, especially my daughters.”
