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.
