Amanda Seyfried and Justin Long spent a relaxed afternoon together over Labor Day weekend, joined by Seyfried’s famous dog companion, Finn.

After taking Finn to get groomed at Tailwaggers & Tailwashers, the new couple went to a nearby Los Angeles Park. Both Seyfried and Long were all smiles as they laid out blankets and took a seat in the shade. Following their trip to the park, the Lovelace actress and the Accepted actor went out for a romantic lunch.

Seyfried and Long were first rumored to be dating mid-August after Long had already joined the 27-year-old actress at the premiere of Lovelace in late July. "Justin came alone and stayed close to Amanda all night," an eyewitness at the event told Us Weekly. "They weren't making out or anything like that, but they were just inseparable during the event. He hung out when she talked with others."

While Seyfried and Long have been friends for some time, the blossoming of their romantic relationship is a recent development. “I'm not positive how they exactly met, but they've known each other for awhile, when they were seeing other people," a source told the entertainment magazine. "They recently started hanging out more, going on date-like activities. They're both busy … but they're seeing where it goes."

Seyfried, who dated her Mama Mia costar Dominic Cooper for over three years, was last linked to Dexter actor Desmond Harrington. Long’s last romance was with House of Cards actress Kate Mara.
