This comes two years after the pair started dating.
Jennifer Garner and businessman John Miller have broken up after almost two years of dating.
Despite ending their relationship, Us Weekly reports they did so on "very amicable terms."
The former couple originally started dating in October 2018, shortly after Jennifer finalised her divorce from then husband - and father of her three children - Ben Affleck.
At the time, a source told Entertainment Tonight, the pair had felt a connection after meeting through mutual friends.
"He is warm, fun and incredibly smart," the source said of Miller, who's the CEO of Cali Group - a tech company,
"He is a real success in the business world and has no interest in being in the entertainment industry."
A year later, a source told US Weekly, “John and Jen are in similar places in their lives and can relate to raising kids after a divorce.”
Jennifer and her ex Ben are parents to daughters, Violet, 14, Seraphina,11, and son Samuel, 8. Meanwhile, John shares two children with ex wife Caroline Campbell.
“They’re on the same page and understand where things stand,” the source said about the Alias actress and her businessman partner.
In the past, sources close to the actress told ET, "Jen feels so lucky to have met John and their relationship only continues to grow."
"They both wanted to take it slow, but it has gotten serious and they couldn't be happier. John's been at their Palisades house so much lately. They all [John, Jen and their kids] stay up late playing board games."

"Jen has something very different with John than she had with Ben," the source added.
"She and John are both interested in living a healthy lifestyle, working out and eating well, except for the occasional trip to Chick-fil-A! When they aren't with the kids, they take time on their own seeing movies and having romantic dinners. They've already taken the kids to the mountains together, and Jen's friends describe John as a mountain man. He loves to do outdoorsy things."
Jennifer is yet to make a statement about the break-up, but we are sending her well wishes.
