Ben Affleck Signs Giant 'Gone Girl' Poster While Out in LA

Ben Affleck wears a casual plaid shirt while out and about in Los Angeles on Friday afternoon (May 14).

The 48-year-old actor was spotted dropping off his youngest child, Samuel, for a swimming lesson and while returning to his parked car, was kind enough to sign an enormous poster for his movie, Gone Girl.

Ben starred opposite Rosamund Pike in the 2014 movie, which centered on his character becoming the prime suspect when she goes missing on their fifth wedding anniversary.

The sighting is Ben‘s first since reuniting and spending time with his ex, Jennifer Lopez, in Montana.

The former couple have apparently been emailing each other since before she and Alex Rodriguez called it quits, and just recently, a former rep for Jennifer is revealing that she might even still have the engagement ring Ben once gave her.
