According to reports, Ariana felt betrayed by Pete and doesn't want to take the chance that he'll talk about their breakup yesterday on "SNL" as she just sits by.

Pete addressed his breakup on SNL Saturday night, and had nothing but good things to say about his ex-fiancee.
"Don't get me wrong, I'm not insane, I know I shouldn't be making fun of how anyone looks", Pete later said before his own picture was put on the screen. Both tweets were later deleted.
Then, the comic turned serious during Saturday Night Live's "Weekend Update" segment, saying, "I genuinely wish her all the happiness in the world".
'Now please everybody, go vote on Tuesday'.
