Amanda Seyfried Dating Justin Long? [VIDEO]: 'Lovelace' Actress & 'iSteve' Star's New 'Private' Romance, 'Seeing Where It Goes,' Evidence on Twitter?

Last month, actress Amanda Seyfried opened up to ELLE Magazine about her love life and hinted at her current relationship. The Lovelace star did not reveal the name of her boyfriend at the time, but now reports are alleging that it is none other than Justin Long!

"Justin is super private about his relationships, [so] I'm not positive how they exactly met, but they've known each other for awhile, when they were seeing other people," a source explained to Us. "They recently started hanging out more, going on date-like activities. They're both busy ... but they're seeing where it goes."

"Justin came alone and stayed close to Amanda all night," the insider said of the Lovelace premiere. "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."

Another hint that this relationship is in fact happening is a certain Twitter post from Long:

Adjectives don't do justice to @AmandaSeyfried's fearless + transformative perf in #Lovelace (though I would've been better) -just go see it

Mstars recently reported on Amanda opening up about her love life to ELLE Magazine. Here is an excerpt:

"Everybody I've dated I've been sexually attracted to immediately," she said. "Sparks don't grow-your vagina doesn't become more inclined to wanting someone just because you're around them."

In terms of ex-boyfriend Dominic Cooper, she wasn't too shy about talking about him either!

"We love each other... He'll always be in my life regardless of what his girlfriends or future wife think," she explained. "I'm never going to be with a guy that can't deal with my friendship with him."

But what about her current love life? Amanda opened up about her current relationship, saying, "[He's] someone separate from my industry life- I've known him since he was 16 ... I picture him as the father of my children all the time. But it is a fantasy right now."
