Jon has lived in New York since he and Corinne began dating in mid-2018 after being introduced to each other by mutual friends.
Corinne had told Us in March she would normally be the person to travel and visit Jon in their relationship since he had "more of a 9-to-5" [job] and it was easier for her to pick up and leave L.A. at any time.
Corinne, 27, was reportedly already spotted with a mystery man at Craig's restaurant in West Hollywood, CA, on Saturday in the wake of her split from Jon.
The split may come as a surprise to fans because during her March interview with Us, Corinne had gushed about being "soul mates" with Jon.
Corinne said at the time she envisioned herself getting engaged to Jon down the road and they had already begun looking for the perfect engagement ring.
"It'd be really traumatic if we ever broke up," Corinne told the magazine.
"But not because we're gonna get engaged. I don't know if I was supposed to say that. Well, I mean, I hope so."
She added, "It's time. I told him. I'm like, 'Listen, bro. You got until the end of this year.'"
