Her actor father is only a year older than her new husband.
Their secret marriage was revealed by Irena Medavoy, wife of Black Swan producer Mike Medavoy, after posting a congratulatory message online.
In a post on Instagram, she wrote: “We are so happy that @leilageorge #seanpenn got married.
” We love you. Thank you for being like family, son to mike, we are delighted to find your soul mate, true partner @coreresponse, true love who also changes the world for the better.
“You are meant to be together God bless you both and the family you have joined. Introducing # Penn’s Wedding ”.
She posted a photo that appeared to be the wedding rings of the newlyweds.
The couple also received a congratulatory message from Josh Brolin, Penn’s friend and Milk’s co-star.
In a post on his Instagram Stories, the actor wrote, “Happy marriage of the lovebirds. Our greetings to a beautiful wedding. Sean and Leila. ”
This is Penn’s third trip down the aisle. He was previously married to pop superstar Madonna from 1985 to 1989 before marrying House Of Cards actress Robin Wright.
The couple married for 14 years and became parents to two children before divorcing in 2010.
He was also dating fellow Hollywood star Charlize Theron from 2013 to 2015.
The actor recently admitted that he can be a “difficult” person to be around, and expressed his love for Leila during an appearance on The Howard Stern Show in June.
He said, “Am I picky? Yeah I think so. I will say that I am a person who feels and expresses energetically, I have misled people into believing that everything is for me.
“I think the interview you are talking about would be a lady named Leila George, she knows me better than I do at that level, that doesn’t mean I agree with her perceptions but I certainly find them fascinating. ”
He then called the actress “the girl of my life”.
