Amanda Seyfried’s new man isn’t all that new–not to her, anyway. She and Thomas Sadoski first met last year, when they starred on Broadway together in The Way We Get By.

The pair rekindled their friendship on the set of their new film, The Last Word, and now are officially dating.

“Amanda and Thomas are definitely dating right now. She’s no longer single,” a source tells Us Weekly.

The publication goes on to report that Amanda Seyfried and Thomas Sadoski had the perfect opportunity to learn if they wanted to spend more time together, since they spent lots of time together on the set of the upcoming film.

“Making movies is two solid months of 12, 14-hour days. I mean, it can ruin your relationship,” she said in recent months.
