If Ellen DeGeneres is known for anything, aside from her killer dance moves, of course, it's her embrace of the fun, the silly, the spontaneous. Or the extremely well-thought-out Halloween costume.
In fact, she goes all out for Halloween, never failing to get into the spirit of the spooky holiday with a well-timed homage to an iconic figure, a concept or whatever is the big thing at that moment in pop culture.
Her embrace of Halloween has resulted in some memorable looks over the years—including 2016, when she dressed up as Sia and guest Heidi Klum donned a nude leotard and writhed around as the artist's No. 1 dance muse, Maddie Ziegler.
So, as much as we enjoy Ellen being herself on daily basis, it can be awfully fun to watch her pretend to be other people. Check out her most memorable costumes through the years—and happy Halloween!
