This year, celebrities pulled out all the stops for Halloween [2], and we're adding Lizzo [3] to the list. After revealing her Skittles costume [4], she upped the ante by dressing as a DNA test in reference to her No. 1 single, "Truth Hurts [5]." The songstress shared a hilarious Instagram clip on Halloween [6], in which she rocks a giant colorful box and "calculates" the DNA results of hairstylist Shelby Swain [7]. Her popular tune begins to play right before she reveals that Shelby is — you guessed it — 100 percent that b*tch. "IDK y'all ... this year for Halloween [8] I decided to not wear a costume," she joked in the caption.

When Lizzo [9] wasn't looking good as hell in her costumes, she was getting into the Halloween spirit on The Ellen DeGeneres Show [10]. During the annual haunted house segment, she joined producer Andy Lassner for a frightening trip through Universal Studios' Pandora's Cabinet of Curiosity. Although she was clearly scared out of her mind [11], we're sure her DNA test would still say she's "that b*tch" through and through.
