Amanda Seyfried and Justin Long are apparently laced up in love, with Us Weekly reporting that the two have started seeing one another.

A source tells the magazine that Long, who most recently starred in "A Case of You," which he co-wrote, attended a July 30 "Lovelace" premiere event with Seyfried, where "they were just inseparable." Long also tweeted a rave review of Seyfried's triple-X performance in the biopic on August 10:

Another insider adds that although their relationship is still in the beginning stages, Long, 35, and Seyfried, 27, have known one another for some time. "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 source reveals. "They recently started hanging out more, going on date-like activities. ... [T]hey're seeing where it goes."

Seyfried's famous ex-boyfriends include Desmond Harrington, Ryan Phillippe, Josh Hartnett, and Dominic Cooper, and Long has romanced the likes of Kate Mara and Drew Barrymore.
