Paris Hilton wowed fans with her Katy Perry Halloween transformation as she slipped into one of the pop star's iconic looks. 

In a video shared on her Instagram story, Paris donned a faux leather red bodysuit adorned with stylish cut-outs and frilly trousers, capturing Katy Perry's signature style perfectly. 

However, the standout feature was her mushroom-shaped hat, completing the look.

Paris was accompanied by her husband, Carter Reum, and son, who joined her in dressing up as adorable mushrooms. 

The socialite's Halloween costume versatility was evident, having previously paid tribute to Britney Spears with a rendition of her iconic Toxic outfit for "round 1" of Halloween celebrations. 

In her Instagram post, she captioned the Katy Perry look with, "Halloween Round 2 as another one of my iconic Queens @KatyPerry #IconsOnly."
