Darius McCrary -- Ex-Wife Perjures Herself ... Retracts Claim of Violence Against Son

EXCLUSIVE

Darius McCrary's ex-wife says she lied when she swore under oath he beat his kid.

Karrine "Superhead" Steffans filed legal docs -- obtained by TMZ -- admitting she perjured herself when she joined forces with Darius' baby mama in a child support war over their young son. Karrine claimed she saw her ex beat the boy with a spoon.  

But Karrine had a change of heart, and filed new legal docs saying she lied because she was "hurt and upset" over their divorce. Tell that to a judge in a perjury case.

Sometimes allies can shoot you in the foot.
