Jennifer Garner's boyfriend, John Miller, appears to be taking a stand after photos surfaced of Garner spending quality time with her ex-partner, Ben Affleck.
The pictures, published by the Daily Mail, show Garner and Affleck displaying affection at their son Samuel's 13th birthday celebration.
The sighting has sparked widespread attention, particularly given Affleck's recent split from Jennifer Lopez.
Sources close to Miller claim he's confident in Garner's fidelity, but the growing closeness between Garner and Affleck has raised eyebrows.
"Everyone in showbiz says so," an insider noted, suggesting Miller should be worried. Miller's response to the situation has been telling, as he was recently spotted with his ex-wife, Caroline Campbell.
The photos, obtained by TMZ, show Miller and Campbell in a car headed to an unknown destination. The couple was married from 2005 to 2011, but the reasons for their separation remain unclear.
Miller began dating Garner in 2018, following her separation from Affleck.
Despite keeping their relationship largely out of the spotlight, the recent developments have sparked speculation about the state of their relationship.
