For a second time, Bennifer is officially over.

Singer Jennifer Lopez filed for divorce from actor Ben Affleck on Tuesday after roughly two years of marriage. Their on-again, off-again relationship spans two decades, long enough to spark nostalgia for some who came of age with the pop culture icons during their first romantic go-around.

Between their first relationship in the early 2000s and getting married in Las Vegas in 2022, both Lopez and Affleck had other marriages, children and career milestones.

Here is a complete timeline on how Bennifer came to be, broke up, got back together and broke up (again).

2001-2002: Meeting on set

Affleck and Lopez connected on the set of “Gigli.” While filming the movie, Lopez was married to her second husband, Cris Judd.

Affleck later told Vanity Fair in 2003 that their relationship was rooted in a strong friendship that they developed as co-stars.

“When I met her we became really, really, really good friends,” he told the publication. “But at first, because she was married, there was no thought of a romantic relationship, so that created the opportunity to get to know each other without any of the falseness that goes with courtship because you’re trying to make a good impression. I didn’t try to change anything about myself, and she didn’t either. We became really good friends in a way that was very comfortable.”

Summer 2002: The ‘Bennifer’ era begins

Lopez filed for divorce from Judd in July 2002.

That summer, paparazzi spotted Lopez and Affleck getting romantic at a birthday party for the singer. It’s around this time they are believed to have started dating.

Just before they were set to say “I do,” the couple released a statement saying they were postponing their nuptials.

“Due to the excessive media attention surrounding our wedding, we have decided to postpone the date,” the couple said in a joint statement at the time, according to CBS News. “When we found ourselves seriously contemplating hiring three separate ‘decoy brides’ at three different locations, we realized that something was awry. We began to feel that the spirit of what should have been the happiest day of our lives could be compromised. We felt what should have been a joyful and sacred day could be spoiled for us, our families, and our friends.”
