When it comes to Katy Perry‘s Halloween costume, Hillary Clinton is with her.
Perry, 32, donned prosthetics, a blond wig and one of the Democratic presidential hopeful’s signature pantsuits for Kate Hudson‘s Halloween party on Friday night.
“Oh my, look at that!” Clinton gushed to Extra on Monday when host Tracey Edmonds showed her a photo of the “Firework” singer.
Perry has been a longstanding Clinton supporter, performing at fundraisers and at the Democratic National Convention in July, as well as campaigning for her at colleges.
“This is shocking — oh, my gosh,” Clinton, 69, stammered. “This is great! She could be me when we finish the campaign.”
