Green revealed in May that he and Fox broke up in late 2019, more than nine years after their marriage.
This isn't the first time the former couple have stepped into the shadows online since the split.
In August, Fox posted a photo of herself with her new boyfriend on Instagram, Kelly machine gun, with towels wrapped around their waists, writing: "A beautiful, aching boy ... My heart is yours." Green appeared to counter his post with one of his own, a slideshow of photos of their boys as well as a photo of his 18-year-old son. Kassius Marcil-Green, writing: "Painfully beautiful boys ... My heart is yours."
During the majority of the time they were together, Fox and Green largely refrained from posting any footage of their three sons, Journey, Bodhi, 6 and Noah, 8, although in recent years they have shared family photos showing the children celebrating Halloween. Fox posted on her Instagram just before last year's vacation photos of her, Green and their children in disguise at Disneyland.
On Sunday, she didn't post a 2020 Halloween photo of the kids, preferring to share a photo of herself and her friends in costumes.
Over the past few months, Green has posted numerous photos of his and Fox's sons on social media.
