Writing a lovestruck statement in the form of a poem after the nuptials, Pamela Anderson dubbed Jon Peters as "the original 'bad boy' of Hollywood."
"No one compares. I love him deeply like family," Anderson wrote to The Hollywood Reporter.
Canadian-born Pamela Anderson, 52, has previously been married to rockers Tommy Lee and Kid Rock. She twice wed professional poker player Rick Salomon.
More recently she dated French soccer star Adil Rami, with whom she lived in France.
Jon Peters, 74, a former hair stylist, rose to Hollywood prominence after a high-profile romance with Barbra Streisand, going on to produce her 1976 version of A Star Is Born.
He subsequently oversaw the Tim Burton Batman films in the 1980s and 1990s, and brought another DC comic books icon back to the screen in 2006's Superman Returns.
He was co-chairman of Columbia Pictures for a stint in the 1990s.
Jon Peters told THR: "There are beautiful girls everywhere. I could have my pick, but for 35 years I've only wanted Pamela."
Jon Peters reportedly first met Pamela Anderson at the Playboy Mansion in the 1980s, and proposed to her shortly after.
But until recently the pair had grown apart. When asked about their relationship in an interview with THR in 2017, Peters said: "You'll have to do your research. I can't even remember anymore."
The wedding is also Peters' fifth time at the altar, with his most recent marriage ending in 2004.
"His life used to scare me. So much for a girl like me," wrote Anderson. "Now I've seen more of life and realize. He's been there all along."
Pamela Anderson, a prolific social media user, has yet to mention the wedding on those platforms.
But on Monday, she posted a series of black-and-white photo portraits on Instagram captioned with romance-themed quotes.
One read: "Love is in the air."
