'Real Housewife' Joanna Krupa sounds like she's ready to physically duke it out with archenemy Brandi Glanville ... calling her a trailer trash fame whore who is a European model wannabe.
Krupa went ballistic when our photog asked about Brandi, who trashed her on Andy Cohen's show. Glanville insinuated Cohen got food poisoning from bad fish ... code for Krupa's smelly vagina.
Krupa went for the jugular, telling us Brandi is so pathetic there's no room for doubt on why Eddie Cibrian dumped her.
Watch the video. It has all the makings of a fabulous bitch fight.
