The celebrity blogger had initially claimed that will.i.am had been involved in the physical altercation after a verbal spat but the singer twice denied the allegation.
will.i.am's manager Polo Molina has since been charged with assaulting Hilton after he handed himself over to authorities.
In a 12-minute video statement on his website, Hilton broke down in tears and denied exploiting the incident for media attention.
Hilton said: "I called the police. Even if GaGa had a bodyguard, what if one of these people had a gun and came and wanted to do something else?
"So when the police are taking their time and not coming and I'm freaking out I took to Twitter because I was in shock and I felt helpless.
"I am a human being and no-one deserves to be treated that way. Violence is never the answer."
He added: "And f**k you, will.i.am, for lying. Shame on you. God is looking down on you and shaming you. And you know what, I may not making everyone happy or proud, but I would never hurt someone like that.
"And I did not deserve what happened to me. F**k you, you f**king coward and f**k you both. I have lost all respect for all of you and the Black Eyed Peas. And Fergie, you're fugly bitch!"
