Amanda Seyfried is dating He's Just Not That Into You actor Justin Long, according to UsWeekly.
The two have reportedly known each other for awhile but began spending more time together.
"They recently started hanging out more, going on date-like activies," a source tells the mag. "They're both busy...but they're seeing where it goes."
Amanda and Justin were "inseparable" at her Lovelace premiere on July 30, and Justin even gave her a shoutout on Twitter.
"Adjectives don't do justice to @AmandaSeyfried's fearless + transformative perf in #Lovelace (though I would've been better) Just go see it," the 35-year-old Tweeted.
Justin was linked to Kate Mara last summer, while Amanda previously dated Ryan Phillippe.
Do you think they make a good pair?
