Affleck, aged 51, and Garner, also 51, are renowned as proud parents of their three children.
Throughout the years, the former couple has been diligent in shielding their children from the public eye, particularly in relation to paparazzi snapshots and social media exposure.
However, it's now been revealed that Affleck and Garner's middle child has opted to change their name...
Ben Affleck And Jennifer Garner's Child Reveals New Name Despite their separation in 2015 after a decade of marriage, the Gone Girl actor and the 13 Going on 30 star continue to co-parent their children harmoniously.
Affleck and his ex-wife Garner share three children: Violet, 18, formerly known as Seraphina Rose, 15, and Samuel, 12.
Ben Affleck And Jennifer Garner's Child Reveals New Name The Good Will Hunting actor has extended his family by blending it with his new wife Jennifer Lopez's 16-year-old twins, Maximilian 'Max' David Muñiz and Emme Maribel Muñiz.
It appears that all the step-siblings share a harmonious relationship, as Lopez mentioned to Vogue Latin America: "The transition is a process that needs to be handled with so much care. They have so many feelings. They're teens."
The 'On The Floor' singer continued: "But it's going really well so far. What I hope to cultivate with our family is that his kids have a new ally in me and my kids have a new ally in him, someone who really loves and cares about them but can have a different perspective and help me see things that I can't see with my kids because I'm so emotionally tied up."
Ben Affleck And Jennifer Garner's Child Reveals New Name Lopez's followers have observed her use of non-binary pronouns when talking about Emme.
The 'Ain't Your Mama' singer shared with the audience during a Los Angeles performance: "The last time we performed together was in a big stadium like this and I ask them to sing with me all the time, and they won't. So this is a very special occasion."
"They are very, very busy, booked and pricey," she joked, adding: "They cost me when they come out. But they're worth every single penny because they're my favourite duet partner of all time. So if you will indulge me."
Emme utilized a rainbow microphone during the performance.
Ben Affleck And Jennifer Garner's Child Reveals New Name Meanwhile, Affleck and Garner have actively pursued measures to minimize their children's exposure to the public eye.
"When they were smaller and there were things out there that were shocking, my request to them was always, 'Let dad and I talk you through whatever it is'," Garner previously told The Hollywood Reporter.
"I'd tell them, 'If you see an image on the front of a magazine, I'll look at it with you and we'll process all the scary feelings that come up together'."
Ben Affleck And Jennifer Garner's Child Reveals New Name Affleck reiterated this stance in an interview with the Los Angeles Times: "I got to a place where public perception was so different from who I am that I just stopped reading and stopped caring."
"But then, as my kids got older and started seeing the internet themselves, that's the difficult part."
"Even the 'Sad Affleck' meme – that was funny to me. I mean, there's nobody who hasn't felt that way at a junket. But then my kids see it and I think, 'Oh, are they going to think their dad is fundamentally sad or they have to worry about me?'. That's really tough."
Affleck has also told Good Morning America: "I will be long dead and someone will ask my kids, 'What was your dad like?' and that is when I will know what my life was worth."
Despite the former couple's efforts to shield their children from public attention during their early years, one of their offspring is now grabbing headlines.
Ben Affleck And Jennifer Garner's Child Reveals New Name Affleck and Garner's second child, Seraphina Rose Elizabeth Affleck, was born on January 6, 2009.
Following their parents' separation, it seems they have embraced their role in a blended family, even playing a significant part in the Affleck-Lopez wedding.
And now, Affleck and Garner's middle child has unveiled a new name.
During their grandfather's memorial service last weekend, which was streamed live on Facebook, the teenager appeared in a black suit with a buzzcut hairstyle.
The service was held in memory of Garner's father, William Jack Garner, who recently passed away.
At the memorial, Fin introduced themselves by their new name.
Speaking from the lectern, Fin said: "Hello my name is Fin Affleck," they then proceeded to read Chapter 16, Verse 8 from the 'Book of Proverbs': "Better is a little with righteousness, than a large income with injustice."
Ben Affleck And Jennifer Garner's Child Reveals New Name Fin has developed a close bond with J-Lo's 16-year-old child Emme, who prefers gender-neutral pronouns.
While Fin has not made any statements regarding their gender identity, Affleck has consistently supported LGBTQ+ rights.
In a previous statement quoted in The Quotable Queer, he expressed his hope that future generations would view the LGBTQ+ marriage debate as antiquated.
According to Salon, he has also stated that suggesting members of the transgender community are not entitled to equal rights is "outrageous and offensive."
