The overly unleashed former tween pop star made her own mark on the holiday Wednesday by dressing as Lil Kim from the 1999 MTV Video Music Awards, complete with a single purple pasty on her less-ample-than-Kim's left breast.
That, of course, came after she tweeted obscene pumpkins carved to depict boy-on-girl and girl-on-girl sex acts to her millions of followers Wednesday (with the warning "xxxxxxplicit pornkinzzz #beware). And according to the New York Daily News, her male assistant got stuck wearing Miley's 2013 VMAs tongue-flashing teddy-bear onesie.
There was simply no escape from the cult of Miley.
Jenny McCarthy cut to the chase by dressing simply as Miley's tongue, tweeting a picture of the getup Thursday morning.
"Yes indeed I am Miley's tongue," she wrote, then referred to the singer's "Wrecking Ball" video: "I craved sledgehammers all day."
Joan Rivers, meanwhile, made her Miley even scarier than the real thing, showing up lumps and all as Miley-in-latex on E!'s "Fashion Police" Wednesday.
For Playboy's Halloween party over the weekend, Hugh Hefner and wife Crystal dressed up as Miley and Robin Thicke at the 2013 VMAs and snapped shots with Hef clad in Robin's "Beetlejuice"-style stripes and Crystal in a nude minidress, twerking him a la Miley.
At the same party, Paris Hilton donned a version of Miley's "before" costume from the VMAs — that devilish teddy-bear onesie.
Meanwhile, on Thursday, Kelly Ripa and Michael Strahan brought the Cyrus-Thicke pairing 100% mainstream on "Live With Kelly and Michael." We think Strahan one-upped Hef with suit authenticity, as the Playboy honcho's duds clearly displayed a prison identification number.
So remember tonight, if you're going out as Miley Cyrus, Hollywood has already been there, done that. And please, please, think of the children.
