We can always count on Halsey to steam up our screens with her sexy snaps, and the same can be said about the majority of her Halloween costumes. The 24-year-old singer has dressed up as Poison Ivy, Harley Quinn, and Princess Leia over the years, and this year she's already blessed us with some new ones. Will there be more to come? In 2016, Halsey had a total of four different costumes, so who knows? She may even surprise us with five this year. For now, take a look at Halsey's Halloween costumes from years past ahead.
