Amanda Seyfried and Justin Long are certainly fueling those dating rumors!

On Thursday night the "Lovelace" star and "iSteve" actor were spotted out to dinner at Cecconi's in West Hollywood, witnesses confirm to omg!.

"It was clearly a date," one onlooker says. "They were drinking white wine, laughing, and both seemed really into each other. They were definitely flirty — it was cute!"

The fellow diner also described Seyfried, 27, as looking "casual, but gorgeous," in minimal makeup, a black shirt, and a hat, as she enjoyed an Italian meal with Long.

Long, 35, was first spotted cozying up to Amanda at an after-party for her film "Lovelace" on July 30 in New York City.

Us Weekly then reported yesterday that Justin and Amanda were indeed a couple.

"They recently started hanging out more, going on date-like activities," a source told Us Weekly. "They're both busy … but they're seeing where it goes."

Sources also confirm to omg! that the two are dating, but it's in the early stages.

"It's new," an insider close to Amanda tells omg!. "Work is keeping her really busy so who knows where it will go, but they are having fun."

Amanda has previously dated her "Mamma Mia!" co-star Dominic Cooper as well as Ryan Philippe. In the August issue of Elle, Seyfried admitted she was seeing someone, but didn't reveal who.

"[He's] someone separate from my industry life — I've known him since he was 16," she exclaimed. "I picture him as the father of my children all the time. But it is a fantasy right now."

Justin was on-again, off-again with Drew Barrymore for years before briefly romancing "House of Cards" actress Kate Mara.
