Krayzie Bone needs prayers.

The Bones Thugs-n-Harmony member checked himself into a Los Angeles area hospital Friday after he began coughing up blood.

Krayzie suffers from, a rare inflammatory disease that causes the organs to become covered in lumpy nodes called granuloma.  A CAT scan revealed that an artery in one of his lungs had burst.

The doctors weren't able to stop the bleeding, and Krayzie was sedated and put on a breathing tube.

The 50-year-old is listed in critical condition.
