Hannah Brown stepped up her game on Dancing With the Stars [1] on Monday. After receiving several critiques from the judges these past few weeks, the former Bachelorette [2] came out swinging during boy band and girl group night. For her second routine of the night [3], Brown and her partner Alan Bersten danced to one of the biggest boy bands in the world right now, K-pop group [4] BTS. The dancing duo [5] looked super in sync as they moved to the group's song, "Boy With Luv" featuring Halsey. Clearly the catchy hit was a good choice, because it ended up giving Brown a nearly perfect score! Watch her sassy routine above.
