In Naya Rivera's memoir, Sorry Not Sorry: Dreams, Mistakes, and Making Up, she claimed she and Lea Michele didn't get along while filming Glee, especially during Season 6. Rivera wrote, "If I'd complained about anyone or anything, she'd assumed I was bitching about her. Soon, she started to ignore me, and eventually it got to the point where she didn't say a word to me for all of Season 6."
Rivera also wrote about Michele's reaction when Santana started getting more onscreen time: "As the show progressed, though, that friendship started to break down, especially as Santana moved from a background character to one with bigger plot lines and more screen time. I think Rachel—erm, I mean Lea—didn't like sharing the spotlight."
