The adorable couple have two children together -- John, 21 and Matthew, 23.
The Grinder star appeared on The Ellen Degeneres Show shortly after John’s 21st birthday, and admitted that the Las Vegas celebration got a bit crazy.
"There was lots of love, lots of pride, lots of happiness, lots of Visine," Lowe said. "There might have been some vomiting. There might have been one of the guests meeting a young lady and getting their wallet stolen ... I'm just saying, it's Las Vegas."
"It got wild for these kids," he added.
Lowe shared multiple photos on Instagram following the epic celebration, including a father and son portrait, as well as a photo of the entire family with a birthday cake.
