Hilton said he got into an argument with band members Fergie and will.i.am at the Cobra nightclub early Monday morning and was punched outside by Polo Molina, the band's tour manager. They were at the club following a Sunday night video awards show.
Molina turned himself in and has been charged with assaulting Hilton, Toronto Police Constable Tony Vella said. Molina is due in court Aug. 5.
Hilton, whose real name is Mario Lavandeira, complained about the incident on the microblogging site Twitter. He tweeted at 4 a.m.: "I am bleeding. Please, I need to file a police report. No joke."
Hilton, who is openly gay, said in interview with The Associated Press that he called will.i.am a "faggot," a gay slur, inside the club after the musician told the blogger not to write about his band on his Web site.
"He was like 'You need to respect me.' He was in my face. He was obviously trying to intimidate me and scare me," Hilton said. "I was like 'I don't need to respect you. I don't respect you and I did say this, and I knew that it would be the worst thing I could possibly say to him because he was acting the way he was. I said 'You know what, I don't respect you and you're gay and stop being such a faggot."'
Will.i.am said in a video posting on dipdive.com that he came to Hilton with respect and was called a "faggot."
Hilton, who was at the club with Lady Gaga, said he then left the club and was punched from behind. The pop stars and the blogger were among celebrities in Toronto for the MuchMusic Video Awards on Sunday night.
A spokeswoman for the Black Eyed Peas declined comment.
