Avril Lavigne is pissed at Perez Hilton. Why, we don't know. But she's so upset that she's created a site called PerezLavigne, on which she says to "users," "[Perez] thinks in his own little world that he is the best and he makes everybody look silly on his Blog. But in reality he is more silly! His insults have really hurt me so please help me to kick Perez in the ass." Uh, any takers? [PerezLavigne.com]
