Katy Perry is not just #WithHer—she #IsHer!

The 32-year-old pop star transformed herself into 69-year-old Democratic presidential candidate Hillary Clinton on Friday, October 28, just in time for her pal Kate Hudson's annual Halloween bash.

Wearing facial prosthetics and a very telling blonde wig, Perry donned a red pantsuit for the occasion, where she was also flanked by a handful of Secret Service agents as well as a friend dressed as Bill Clinton.

Meanwhile, her boyfriend dressed up as clownish version of Donald Trump. (Or rather, a more clownish version.)

On Instagram, the "Rise" singer teased her transformation to fans, sharing a photo of herself in costume in the makeup chair and captioning it, "Having a little pre party before I take office. #IMWITHME"

Mrs. Clinton if you're nasty, indeed. See below:
