The 24-year-old posted a lengthy message to Katie, 36, on Twitter, after the former glamour model blasted Jodie, also 36, earlier today.
After Jodie criticised the mum-of-five for having children with different dads, Katie accused the bodybuilder of trying to copy her and said she has a nose like a builders elbow.
Wading into the argument, Josie fumed: "[Katie] You seem obsessed with the fact that people want to copy you, like your something so special that no one can have a mind of their own [sic].
"If you was really my idol I would have instead got my f***y out for a magazine like you did or had a washed up boy band member penetrate me with his big toe [sic]."
Ouch. Josie was of course referring to the leaked intimate tape rumoured to feature Katie and ex-boyfriend Dane Bowers.
Slamming Katie's choice of men, Josie continued: "Jodie's probably single through choice – she wants the right guy, one that can speak English, doesn't cross dress nor one that sh*gs her best friends [sic].
"It's time to face reality babe… Your sell by date is approaching. Best of luck in the future babes."
What do you think of Josie's comments?
