What a tearjerker! After taking a swipe at her marriage to Ben Affleck, Jennifer Lopez performed a heartbreaking rendition of Lana Del Rey's iconic song Young and Beautiful during her Las Vegas residency, which began on New Year's Eve. If you don't know, lyrics to the song go: "Will you still love me when I'm no longer young and beautiful? / Will you still love me when I got nothing but my aching soul? / I know you will, I know you will, I know that you will / Will you still love me when I'm no longer beautiful?"
