Halsey has covered the Jonas Brothers [1], Frank Ocean, Justin Bieber, and so many more artists, but her latest "cover" comes in the form of her own song, "Without Me." Last week, the 24-year-old artist stopped by the UK's Capital FM to dabble in some celebrity impressions, and she did not disappoint. From Ariana Grande [2]'s "yuh" to Justin Bieber's hair flip and even Lady Gaga [3]'s famous nose touch from A Star Is Born [4], Halsey nails it, all while singing "Without Me." The best moment, however, comes when she rocks out as Miley Cyrus [5]. Watch the cute video above, then check out Halsey's greatest covers [6].
