"18 years," the caption read, along with a pair of multi-colored sparkling emojis. "#heckyes."

Moder hasn't made many appearances on Roberts' Instagram, although he did appear in silhouette form in a Father's Day tribute from the Oscar-winning actress.

Roberts and Moder have shared three children: Twins Phinnaeus and Hazel, 15, and Henry, 13.

Roberts has popped up occasionally on Morder's page as well, most recently in a goofy family pic.
