Amanda Seyfried gets cosy with Justin Long

New York: Actress Amanda Seyfried and actor Justin Long were reportedly almost inseparable at the premiere of her latest film `Lovelace` here.

The duo was even spotted getting cosy in a corner at the after-party.

Seyfried, 27, and 35-year-old Long secluded themselves from the rest of the guests at the celebratory after-party, reports

"They were hanging out at the after-party at Refinery Rooftop till closing time. They looked cosy in a corner," a source told the New York Post newspaper.

Despite their apparent closeness, a friend of the actress insists that Seyfried and Long are just friends at the moment.

Seyfried has previously dated actors Ryan Phillippe and Dominic Cooper, while Long was in a long-term relationship with actress Drew Barrymore that ended in 2010.
