The former “Beverly Hills, 90210” star shared a photo of himself enjoying breakfast in bed with his three sons Noah, 7, Bodhi, 6, and Journey, 3, and wrote, “My heart ❤️ Happy Fathers Day everyone. My oldest text me at 12:21am this morning”

Green, 46, was referring to his oldest son Kassius, 18, whom he shares with ex Vanessa Marcil. In 2018, Marcil claimed Green “threw out” their son’s room and wouldn’t allow him to spend time with Fox and his other sons.

“Kass no longer has a bedroom at their house starting 5 years ago,” she wrote on Instagram. “He hasn’t ever seen Megan again or met his youngest brother. He’s not allowed to know where they live anymore. Isn’t invited to see them on holidays.”

It’s unclear when Kassius and Green made amends, though his shout out to his oldest son comes after he confirmed at the end of May that his marriage to Megan Fox had ended.

While he’s single — a rep for Courtney Stodden denied anything romantic was going on between them after they were spotted at lunch together — Fox has moved on with Machine Gun Kelly.

Fox and Kelly, who starred together in his music video for “Bloody Valentine,” confirmed their romance when they were photographed kissing earlier this month.
