Raging Bulls Clipart Was Vickie Lamotta Really In Raging Bull?

Was vickie lamotta really in raging bull? - raging bulls clipart

I heard the real Vickie LaMotta (wife of boxer Jake LaMotta) was done in the Martin Scorsese film Raging Bull. I heard he was a backup or something. Does anyone know if thats true? I have also heard that they do not actually deceive him in real life, true or false? Any information is greatly appreciated.
