Megan Fox is being hit with backlash for disobeying SAG-AFTRA's rules about pop culture Halloween costumes amid the ongoing strike in Hollywood.

SAG-AFTRA strongly urged union members and allies not to dress up as TV and movie characters in hopes of blocking struck studios and streamers from getting any free publicity.

Keep posturing for stupid s--t, pretty lady," Walter tweeted. 

"Meanwhile we'll be working 10 hours a day - unpaid - to get basic contract earners a fair deal."

Paige McGarvin, also sounded off, leaving a comment under Fox's post that read.
