Their red hot romance first sizzled in 2002 only to come to an abrupt end in 2004, but this year, the on-again couple surprised fans everywhere when they decided to give it another shot more than 15 years later.
Scroll through the gallery below for everything you need to know about the timeline of Jennifer Lopez and Ben Affleck's relationship through 2021.
They Meet (2001)
First sparks! The "On the Floor" singer and the Good Will Hunting star met in 2001 while costarring in the movie Gigli.
Lopez was married to Criss Judd at the time, which Affleck later said allowed them to become "really, really good friends" and to get to know each other "without any of the falseness that goes with courtship".
In July 2022, J.Lo filed for divorce from her second hubby, and shortly after, she and the Pearl Harbor actor publicly began dating.
They Get Engaged (2002)
2002 was a big year for Bennifer! Affleck famously appeared in Lopez's "Jenny from the Block" music video, and the happy couple also filmed their second movie together — Jersey Girl directed by Kevin Smith.
Following a whirlwind summer relationship, in November, the pair announced their engagement.
"...he is brilliantly smart, loving, charming, affectionate," Lopez gushed to Diane Sawyer in the bombshell interview. "And I just admire him in every way. I respect him. I feel like he teaches me things."
They Breakup (2004)
Calling it quits! Public attention took a toll in 2003, leading the duo to postpone their impending nuptials only days before the wedding was meant to take place.
"We began to feel that the spirit of what should have been the happiest day of our lives could be compromised," they explained in a joint statement. "We felt what should have been a joyful and sacred day could be spoiled for us, our families and our friends."
Only four months later, the couple officially ended their relationship, which J.Lo describes as her "first big heartbreak".
They Move On In New Marriages (2004 & 2005)
Moving on! Following their January split, the Hustlers actress didn't take long before she jumped head first into a brand new relationship — and planned a new wedding! Lopez married "When I Dream at Night" singer Marc Anthony in June of 2004.
Affleck wasn't far behind. After costarring alongside Jennifer Garner in Elektra the year before, the high profile pair began dating, and tied the knot in 2005.

Ben Looks At Engagement Rings (August 2021)
Later that summer, it looked like Mr. Affleck might be considering popping that big question to his leading lady when he was spotted browsing engagement rings at Tiffany's in Century City, Calif., accompanied by his mother and his son.
This came only two months after a source spilled the pair may make it official sooner rather than later. “Let’s be honest, the new relationship might technically only be a few weeks old, but in reality they are picking up where they left off. Jen and Ben both know everything about each other — the good, the bad and the ugly. They are not starting at square one.”
First Red Carpet Appearance Together (September 2021)

“Once it was clear that Ben and Lopez were serious about getting back together, Jennifer reached out," an insider told Radar. "When you have children with an ex and that person starts dating again, all three of you are linked together like it or not. Jennifer was determined to make sure that she had a relationship with J. Lo, if for nothing else, so that things were not awkward for her kids."

Ben Affleck’s Controversial Howard Stern Interview (December 2021)
The 49-year-old actor faced backlash after speaking perhaps a little too candidly in an interview with Howard Stern on December 14 in which he seemed to claim he "would probably still be drinking" if he hadn't divorced the mother of his children.
The Triple Frontier star later clarified on The Jimmy Kimmel Show that his quotes were severely taken out of context, and the media twisting his words "hurt his feelings."
"I had gone on and said how much we respect each other and cared about each other and cared about our kids and put them first," he explained, adding the coverage of the interview "made me out to be the worst, most insensitive, stupid awful guy."

Following reports that claimed the Grammy winner was "livid" with her boyfriend over his controversial interview, Lopez was quick to shut down the rumor mill.
"This story is simply not true. It is not how I feel," Lopez told People. "I couldn't have more respect for Ben as a father, a co-parent, and a person."
