After 25 years of marriage, Sylvester Stallone and Jennifer Flavin are getting divorced.

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

Although Stallone and Flavin, 54, started dating in 1988 at a restaurant in Beverly Hills, California, they only got married in 1997.

The three girls they have are Scarlet (20), Sistine (24), and Sophia (25). Seargeoh, a son from Stallone's first marriage to Sasha Czack, is also his child.

Sage, the oldest child he had with Starlin Wright, passed away in 2012. The news of the filing for divorce was originally reported by Closer Weekly.

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