"Broken-Hearted Girl" is a song by American singer Beyoncé for her third studio album I Am... Sasha Fierce (2008). Written by Beyoncé, Kenneth "Babyface" Edmonds, and production duo Stargate, it was initially a classic rhythm and blues song until Babyface changed the arrangement and chords. The track appears on the I Am... disc, including songs which give a behind-the-scenes glimpse of Beyoncé's life stripped of her make-up and celebrity trappings. The song is a midtempo R&B ballad accompanied by piano, strings, and drum machine beats. The lyrics describe heartache and romantic insecurities.
