Jennifer Garner and John Miller are one of Hollywood’s quietest couples.

The 13 Going on 30 actress and the CEO first connected in 2018, shortly before Garner finalized her divorce from Ben Affleck, with whom she shares three kids — Violet, Seraphina and Samuel.

“Although the divorce was just finalized, Jen has considered herself single for a long time. Dating is just a natural step,” a source told PEOPLE at the time. “Jen will always care about Ben and help him be the best dad. She was very ready to move on though. She seems very excited about the future and is in a great place both personally and professionally.”

Miller has also previously been married, having filed for divorce from violinist Caroline Campbell, with whom he shares two kids, in 2011.

By 2020, it seemed that Garner and Miller had split. The following year, however, the couple appeared to be back on when they were spotted spending time together on several occasions.

The pair are incredibly private and have never spoken about their romance publicly, nor have they made any public appearances. Even so, fans are happy to see that they have both found love again.
