Amanda Seyfried: Dating Justin Long?

Amanda Seyfried shows off her toned legs while visiting BBC Radio One on Wednesday (August 14) in London, England.

The 27-year-old actress is reportedly dating actor Justin Long!

“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,” a source told Us Weekly. “They recently started hanging out more, going on date-like activities. They’re both busy … but they’re seeing where it goes.”

Justin reportedly also attended the Lovelace premiere with Amanda. “They weren’t making out or anything like that, but they were just inseparable during the event. He hung out when she talked with others,” the source added.

FYI: Amanda is wearing the Sachin + Babi Joscelina Dress.
