Jennifer Garner finally joined Instagram. Judging from her reported 185 thousand followers, fans seem to be happy. Operating under the handle @jennifer.garner, Refinery 29 reports that her first post was a video. She spells out words on a sign announcing her arrival. Although Garner reportedly swore off Instagram in a 2014 People Magazine article, saying that people likely wouldn't want to see her and her mom friends after kindergarten drop-off, she's changed her tune. Reports say that she joins other celebs like Sienna Miller and Elizabeth Olsen, who also joined "the gram," after initially refusing.
