Earlier this year, Fox revealed that her engagement to MGK had been called off, although the two never officially broke up.

On an episode of Alex Cooper's Call Her Daddy podcast, Fox discussed her 2023 book Pretty Boys Are Poisonous: Poems: A Collection of F**ked Up Fairy Tales, which contains several poems about her relationship with MGK.

"I feel like everyone has such like an opinion on you guys' relationship. You know, you got engaged, then I think it was called off, then we don't know what's going on with you," Cooper told Fox.

"I think what I've learned from being in this relationship is that it's not for public consumption. So I think as of now, I don't have a comment on like, the status of the relationship per se," Fox replied, adding "there will always be a tether to him no matter what."

The so-called "twin flames" met on the set of the movie Midnight in the Switchgrass in March 2020. A few months later, the actress appeared in the music video for MGK's "Bloody Valentine," off his pop-punk record Tickets to My Downfall.

The "Lonely Road" singer popped the question in January 2022.
