Sylvester Stallone and Jennifer Flavin are ending their 25-year marriage

Sylvester Stallone and Jennifer Flavin are divorcing after 25 years of marriage.

Flavin filed a petition "for dissolution of marriage and other relief" from the Rocky actor, 76, on Friday at a court in Palm Beach County, Florida.

Stallone and Flavin, 54, married in 1997, though their relationship originally began in 1988 at a restaurant in Beverly Hills, California.

They share three daughters: Scarlet, 20, Sistine, 24, and Sophia, 25. Stallone is also a father to son Seargeoh from his previous marriage to Sasha Czack. His oldest son Sage, whom he shares with Starlin Wright, died in 2012.

In a statement to PEOPLE, Stallone said, "I love my family. We are amicably and privately addressing these personal issues."

Flavin told PEOPLE, "I'm sad to announce that after 25 years of marriage I have filed for divorce from my husband Sylvester Stallone. While we will no longer be married, I will always cherish the more than 30-year relationship that we shared, and I know we are both committed to our beautiful daughters. I ask for privacy for our family as we amicably move forward."
