Three 6 Mafia Rapper ... WANTED After Allegedly Beating Fiancee

12:50 PM Crunchy's fiancee tells us the rapper never beat her and she never locked herself in a bathroom. She claims there were two other men who caused her injuries, but they fled before cops arrived.

Three 6 Mafia rapper Crunchy Black is a wanted man in Minnesota after cops says he beat his fiancee and then thumbed his nose at the judge.

CB and his lady were in a hotel room in March when guests began hearing thuds and screaming coming from the room. A hotel employee went up to check and found Crunchy's financee had locked herself in the bathroom.

The hotel employee claimed CB's fiancee said she would only come out if Crunchy would "stop beating her." When police arrived, they found blood on the hotel bed and door frame as well as facial injuries.

The rapper was arrested and jailed, but not just for domestic violence. Cops say when he was booked, they found coke in his pocket.

Crunchy was charged with two counts of domestic assault and one count of drug possession ... all felonies. He skipped his November court date so a warrant has now been issued for his arrest.

Three 6 Mafia won an Oscar in 2006 for writing "It's Hard Out Here For A Pimp" ... sure is.
