We did a Covid wedding. By that I mean it was a county commissioner on Zoom and we were at the house, my two children and her brother
“It was Thursday,” the Mystic River star said.
“We did a Covid wedding. By that I mean it was a county commissioner on Zoom and we were at the house, my two children and her brother. And we did it that way.”
Penn has two children – daughter Dylan Frances, 29, and son Hopper Jack, 26 – with ex-wife Robin Wright.
Asked about the benefits of a small wedding, Penn joked: “Let’s say there are socially liberating factors under Covid.”

He was married to House Of Cards star Wright from 1996 to 2010 and to Madonna from 1985 to 1989.
