Halloween 2016 is upon us, which means celebrities will pulling out all the stops (we're looking at you, Heidi Klum!) to show off their creative, silly, sexy and sometimes culturally appropriative (ugh) costumes.

Beyonce dressed up Salt and Pepa-style with daughter Blue Ivy and her mom Tina. Paris Hilton teased the Big Bad Wolf by dressing up as a sassy Little Red Riding Hood, while pop star and actress Hilary Duff previewed another autumnal holiday by dressing as a pilgrim. Seth Rogen did his best Mario impression (the Nintendo character, duh!) while Seth MacFarlane was uncanny as Sesame Street's resident trash grump, Oscar the Grouch.

Other celebrities took to social media to show off their looks, including Kylie Jenner as early 2000s Christina Aguilera, Kate Hudson as "California Girl" Katy Perry, Jenna Dewan-Tatum as a unicorn, Amy Schumer as Dustin from Stranger Things, and more.

Colton Haynes kept up his tradition of "big" Halloween costumes again this year donning prosthetics to be a mildly terrifying Miss Piggy. She took offense in a possible subtweet.
