Fox also supported Kelly's career on Instagram, sharing a link to his new single, "Concert for Aliens," on her story. The actress previously appeared in Kelly's music video for his song "My Bloody Valentine."
The couple, who met on the set of their upcoming movie, Midnight in the Switchgrass, went Instagram official last month when Kelly shared a pic of himself and Fox.
"Waited for eternity to find you again ... ??❤️?," he captioned the photo.
