During a question-and-answer session on his Ask.fm account, Jay said that he has identified as a boy since he was "six or seven" and shared his experiences with other users.
Jay said he has already informed his mother, Andrea Kelly -- but not his father -- about being transgender and that she has given him her full support.
"I came out through a text to my mum and then I told her when I got more comfortable," he said. "I told her because I knew she would love me no matter what, she has not once judged me in life. She always told me that she loved me and to be who I truly am."
Examiner.com reports that Jay wants to have gender reassignment surgery. The website also suggests that R. Kelly isn't exactly aware of his son's situation.
