There's an innocuous lyric on Lemonade that alludes to Jay Z's "other woman."
At the end of one of the more emotionally charged songs on Lemonade, called "Sorry," Beyoncé sings, "he better call Becky with the good hair." There's not much to go off of. Becky could be anyone. All we know is she has good hair. It would've remained that way if it weren't for a fateful Instagram.
