While their film doesn't hit theaters until May 2, the pair made an appearance with costar Jamie Foxx, who plays supervillain Electro in the upcoming flick, and members of Big Brothers and Big Sisters. They took pictures as a twosome, with Foxx and with the kids.
The last time they made an official red-carpet appearance together was about six months ago for opening night of "Brits Off Broadway: Bull."
Garfield, 30, and Stone, 25, who have been dating since they met on the set of "The Amazing Spider-Man" in 2011, will reprise their roles as the titular Marvel superhero and his love interest Gwen Stacy in the upcoming film.
Stone wore a Band of Outsiders suit, chambray shirt and red Kurt Geiger pumps for the occasion, according to E! News, while her British beau kept it casual in a plaid shirt, dark jeans and khaki jacket.
Though the pair didn't share the photos on social media, Foxx was sure to share his thoughts on the day via Instagram.
"Having a great morning at the #AmazingSpiderman fan event with @andrewgarfield83, @emmajeanstone & all of my friends from Big Brother & Big Sisters. #BBSA," the Oscar-winning actor wrote, posting a photo of them posing with a group of kids.
