In February, Kelly released a song, "Don't Let Me Go," in which he addressed Fox's miscarriage.

Fox already shares three children with with ex-husband Brian Austin Green, while Kelly shares a daughter with his ex Emma Cannon.

The couple first revealed their engagement in January 2022. In an interview on "Call Her Daddy" in March, Fox confirmed she and Kelly had at some point called the engagement off, though she wouldn't go into detail about their current relationship status.

"I think that 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 the status of the relationship, per se," she said. "What I can say is, that is what I refer to as being my 'twin soul,' and there will always be a tether to him no matter what."
