Los Angeles, California - Rapper Ray J, who was catapulted to fame alongside then-girlfriend Kim Kardashian through their leaked sex tape, has revealed that his health is in serious trouble.

According to his own statements, the 45-year-old had to undergo surgery for severe pneumonia at the beginning of the year.

Since then, his heart has only been beating at 25% strength, "but as long as I stay focused and stay on the right path, everything will be all right."

But in a new Instagram livestream, Ray J shared even more troubling news: his doctors have told him he only has months to live.

"2027 is definitely a wrap for me," he said. "My health is not OK."

Ray J and a then relatively unknown Kim Kardashian gained significant media attention after the release of their sex tape in 2007.

Even to this day, it's not clear whether the musician alone is behind the leak – or whether Kim and her "momager" Kris Jenner also had a hand in it.

For now, though, Ray J is not thinking about the past. Instead, he's focused on the time he has left.

The Sexy Can I artist attributed his health troubles to substance abuse, saying that he "f**ked up" and the right side of his heart is now "black."
