Amanda Seyfried reportedly dating actor Justin Long

New couple alert! Amanda Seyfried and Justin Long are reportedly dating.

The “Lovelace” star, 27, and the “iSteve” actor, 35, have been spotted together a few times this summer and, according to recent reports, they’ve been all cozy and canoodley.

They were most recently spotted Thursday at Cecconi’s restaurant in West Hollywood looking as if they were on “a dinner date,” a source told People.

“She was in a festive mood,” the source said.

“They were both smiling and looked so happy,” the onlooker said. “She looked like she was very into him.”

On July 30, the pair were seen getting cozy at the Refinery Rooftop lounge after-party for the Cinema Society premiere of “Lovelace.”

Us Weekly reported that the two were “inseparable” at the event.

“Justin came alone and stayed close to Amanda all night,” a source told the mag. “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.”

“Justin is super private about his relationships,” another source told Us. “But they’ve known each other for a while, when they were seeing other people. They recently started hanging out more, going on date-like activities. They’re both busy … but they’re seeing where it goes.”

Long may be private, but he was pretty forthcoming about his thoughts on Seyfried’s turn as “Deep Throat” porn star Linda Lovelace in her latest flick.

“Adjectives don’t do justice to @AmandaSeyfried’s fearless + transformative perf in #Lovelace (though I would’ve been better) -just go see it,” he tweeted Saturday.

Long has been linked to “House of Cards” actress Kate Mara and dated his “Going the Distance” costar Drew Barrymore on and off from 2007 to 2010. Seyfried was recently linked to “Dexter” actor Desmond Harrington and had previously dated Ryan Phillippe and her “Mamma Mia” costar Dominic Cooper, who she famously kissed-and-told about after their three-year romance fizzled in 2010.

Though she said she remains good friends with Cooper (and still loves him), she recently revealed to Elle magazine that she had moved on to someone else. But the “Mean Girls” alum did not indicate who the new mystery man was.

“[He’s] someone separate from my industry life — I’ve known him since he was 16,” Seyfried told the mag. “I picture him as the father of my children all the time. But it is a fantasy right now.”
