The Riverdale star, 26, shared the news on Instagram, posting a picture of her embracing the model and photographer in front of a private jet.
In the shot, the couple appear to be sharing a kiss, with Vaughan’s back turned towards the camera.
Mendes captioned the photo: “That long distance kind of love.”
Vaughan commented with a sad face emoji and a heart.
Mendes, who plays Veronica Lodge in Riverdale, previously dated her co-star Charles Melton, who plays Reggie Mantle.
The pair first confirmed their romance in October 2018 with an Instagram post before reports surfaced in December 2019 that they were taking a break in their relationship.
