Jennifer Garner, the acclaimed actress, has kept her relationship with businessman John Miller largely out of the public eye since they began dating in 2018. The two have dated on and off over the years, maintaining a low profile despite Garner's A-list status. Miller is an attorney and entrepreneur who currently serves as the chairman of Cali Group, a restaurant technology company. Prior to his relationship with Garner, Miller was married to violinist Caroline Campbell, with whom he has two children. Engagement rumors swirled in 2024 when Garner was spotted wearing a diamond ring, but neither she nor Miller have commented on the matter.
Why it matters
