Long also proclaimed his admiration for Seyfried via Twitter, writing, "Adjectives don't do justice to Amanda Seyfried’s fearless + transformative perf in Lovelace."
Seyfried has previously been linked to Dexter actor Desmond Harrington but that quickly fizzled. Prior to Harrington, Seyfried dated British actor Dominic Cooper for more than three years before splitting in 2010, a breakup that initially devastated the actress. Now, however, the pair still remain close friends.
"He’ll always be in my life regardless of what his girlfriends or future wife think. I’m never going to be with a guy that can’t deal with my friendship with him," she told Ellemagazine in a recent interview.
Long, meanwhile, was most recently linked to House of Cards star Kate Mara. Prior to that Long was in an on/off relationship with Drew Barrymore between 2007 and 2010.
