Amanda Seyfried and Justin Long are dating

Amanda Seyfried and Justin Long are reportedly dating.

The ‘Lovelace’ star is "seeing how it goes" with the ‘iSteve’ actor as they spend more time together but he is hesitant to go public with their romance.

A source told Us Weekly magazine: "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, "

The news comes after pals of the 27-year-old actress denied a romance between the pair and insisted they were just friends.

The source confirmed: "They recently started hanging out more, going on date-like activities. They’re both busy but they’re seeing where it goes."

The couple sparked dating rumors after they were virtually "inseparable" at the New York premiere of Amanda’s latest film ‘Lovelace’ last month, where they were spotted secluding themselves from the rest of the guests at the celebratory after-party.

A source said at the time: "They were hanging out at the after-party at Refinery Rooftop till closing time. They looked cozy in a corner."

Amanda has previously dated Ryan Phillippe and Dominic Cooper, while Justin was in a long-term relationship with Drew Barrymore which ended in 2010.
