Fifteen-year-old Elizabeth doesn't hold back when she lip-syncs to Taylor Swift [2] in the car. The die-hard Swiftie took to Tumblr to share a seriously impressive mashup of herself dancing and singing to Taylor's 1989 album, joking that it's "totally chill." Well, Taylor herself posted the video with her reply [3], saying, "Elizabeth is a rare, exotic sub-species of human that must be protected at all costs." After seeing Taylor's comment, Elizabeth freaked out and shared an adorable selfie of her reaction. Watch the video above to see her lip-sync — and her little sister's hysterical videobomb moment — then see Taylor's favorite meme [4] plus the touching letter she wrote to a young fan [5] who lost her mom.
