The "90210" alum posted a cryptic Instagram message after Fox was seen out with Machine Gun Kelly.
The two stars reportedly called it quits in early April, weeks after they were last seen on each other's social media.
The relationship was the actor's first since calling it quits with ex-wife Jenna Dewan.
"The Crown" star, 53, has since started dating 32-year-old Rye Dag Holmboe.
The couple had been engaged since October 2018.
The “God Is a Woman” pop star announced a social media break after she and Pete Davidson called off their engagement.
Is Jelena 2.0 upon us?
Clearly, there’s still a lot of love between them.
"We are and will always be united."
The actress is grateful for all the love.
