Terrence Howard's nasty divorce, just got nastier. Already plagued with allegations of abuse [click here if you missed that], now Terrence claims his wife is racist and often hurled the n-word at him...
Terrence Howard has filed a new declaration in L.A. County Superior Court -- claiming [his wife] Michelle inexplicably turned from a "loving, gentle" person ... into a monster ... who once threatened to have him killed by some violent Russians.
In the docs, Howard notes Michelle is NOT black -- and claims that when she would get upset, she would scream things like, "[I] never wanted to marry a n**ger in the first place" and "[I] definitely didn't want to be the step mother of some n**ger kids."
As TMZ first reported, Howard claims Michelle is trying to extort him over private recordings she allegedly stole from his personal computer -- and in the new docs, T.H. alleges his wife threatened to have him "clipped" if he went to police.
Howard says his wife once bragged, "I have a lot of Russian friends who would do it as a favor."
Howard also claims Michelle has jealousy issues -- and TWICE attacked him with a bottle after accusing Howard of talking with other women. Howard claims he never struck back.
Terrence has asked the court to issue a restraining order against Michelle. A hearing is set for January 17.
