Stars have been celebrating Halloween with political pastiche, retro pop culture references and lashings of metallic body paint.
Both Heidi Klum and Jonathan Ross threw their annual celeb-laden extravaganzas on the proper date for celebrating all things gruesome and ghostly, even though it was a Monday, while the rest of the A-list dug out their scary outfits over the weekend.
Our unofficial costume awards are as follows:
Maximum effort: Katy Perry and Orlando Bloom were committed fully to their Hillary Clinton and Donald Trump homages, complete with fat suits, bleached eyebrows, prosthetics and scarily convincing hairpieces. Uncanny.
Nailing nostalgia: Beyonce and Kylie Jenner both opted to dress as the musical idols of their youth, with Bey looking to '80s hip hop legends Salt-N-Pepa for her outfit, while Kylie Jenner faithfully recreated Christina Aguilera's iconic bikini and chaps combo for her 2002 Dirrty video.
On point political statement: She may have rolled it out weeks before All Hallows' Eve, but Jemima Khan's take on Melania Trump accompanied by a groping Donald is still proving difficult to beat.
Honourable mentions: Cindy Crawford and her family dressing as punks with attitude, and Jenna Dewan Tatum absolutely owning the sparkly unicorn look.
