Celebrity blogger Perez Hilton is accusing Black Eyed Peas frontman Will.I.Am of assault -- but we've learned cops have targeted someone else.After last night's MuchMusic Video Awards in Toronto, Perez posted to his Twitter:

"I was assaulted by Will.I.Am of the Black Eyed Peas and his security guards. I am bleeding. Please, I need to file a police report.

No joke."But cops in Toronto tell us it was the general manager of the Black Eyed Peas -- Polo Molina -- who is under investigation and he turned himself in to police early this morning.

Here's the string of tweets Perez left on his Twitter page during the alleged beatdown early this morning:
