Mendes started dating her "Riverdale" costar Melton in October 2018, but the pair parted ways a little over a year later. She was then in a relationship with photographer Grayson Vaughan and made their romance Instagram official in September 2020. However, the two split shortly thereafter in March 2021, per "Entertainment Tonight."
Currently, Mendes appears to be dating YouTuber Rudy Mancuso. Though the actor hasn't officially confirmed their relationship, she shared a series of photos in November 2022 that included a snap of herself and an unidentified man sharing a poolside kiss. Mendes also spoke about the current state of her love life during a Jan. 26 episode of the "Going Mental" podcast, saying, "I am still in the honeymoon [phase], but it's one of those situations where I feel like I'm really trying to temper myself." She added, "I don't wanna speak above and beyond, but I feel like I've known him my whole life, and that's something I actually have never felt before."
