An speaking of couples, Paris Hilton and Carter Reum did coordinate their Halloween styles at the annual Casamigos Halloween party Oct. 27.

Meanwhile, fans are still waiting to find out the 2023 Halloween look for the OG Queen of Halloween, Heidi Klum, who's become known for her jaw-dropping costumes over the years. The America's Got Talent judge takes the holiday so seriously, she began brainstorming her 2023 back in December.
For Halloween 2022, the supermodel turned heads when she transformed into a worm for her annual holiday party. As for where the outfit ranked on her list of Halloween costumes?
