Miley Cyrus is a proud sister as her younger one Noah Cyrus recently released her new extended play titled The End of Everything. In order to celebrate her sister's victory, Miley donned a black bikini and shook a leg to her new song in a TikTok video. As seen in the video, Miley is descending down an outdoor staircase as she dances along to her younger sister's song "Ghost" and the video effects perfectly suit the song.
