Amanda Seyfried has been getting "cosy" with Justin Long. The 27-year-old actress and the 'Movie 43' star were "almost inseparable" at the premiere of Amanda's new film 'Lovelace', held in New York City on Tuesday night, and then were spotted secluding themselves from the rest of the guests at the celebratory after-party, where they enjoyed some alone time at the Refinery Rooftop lounge. A source told the New York Post newspaper: "They were hanging out at the after-party at Refinery Rooftop till closing time. They looked cosy in a corner." Despite their apparent closeness, a pal of Amanda's insists she and Justin are "just friends" at the moment. Amanda - who portrays porn actress Linda Lovelace, real name Linda Boreman, in the biopic - was joined at the premiere by her co-stars Peter Sarsgaard, Sharon Stone, Chris Noth and Hank Azaria.
