#5: Jay-Z and Beyoncé

Jay-Z cheated on Beyoncé, which she exposed through her album Lemonade and public hints. The infamous elevator incident and “Becky with the good hair” became cultural references.
Queen B doesn’t really give interviews anymore, but her 2016 album Lemonade told us everything we need to know about Jay-Z cheating on her, including (a) that it happened at all and (b) Beyoncé was PISSED. And (c) they worked through it and came out stronger on the other side.
