"Hilton claims they eventually went their separate ways, but later in the night, Will I. Am -- Fergie's bandmate -- saw Hilton and came at him "like a heat seeking missile," demanding Hilton stop writing about Fergie and his band on his PerezHilton.com.
Hilton claims Will and his manager, Polo, followed him outside the club -- and then Polo punched him in the head "2 or 3 times."
Hilton claims when he got hit, he thought to himself, "I think my eye might be falling out of my head."
Perez added this parting shot to Will, "God knows it was not a random fan that hit me ... you are a f**king liar."
