Wu-Tang Affiliated Rapper -- You Can Kiss Your Penis Goodbye ... for Good

Wu-Tang affiliated rapper Andre Johnson is just plain Andre now ... because doctors weren't able to reattach his penis.

TMZ broke the story Johnson -- aka Christ Bearer -- cut his penis off Wednesday morning and then jumped off his 2nd floor North Hollywood apartment balcony. He was rushed to Cedars-Sinai Medical Center but we're told the penis was a lost cause.

Johnson/Christ Bearer is a member of the group Northstar, which was founded by Wu-Tang Clan member RZA. We're told RZA hasn't done work with the group for several years.

Johnson/Christ Bearer is remarkably in stable condition.

As we reported ... several rappers were present during the horrific scene. They say they were not doing any drugs that would cause such a thing. They believe Johnson/Christ Bearer may have mental issues.
