The Love the Coopers actress has recently started dating Thomas Sadoski, PEOPLE has confirmed. The couple are currently costarring together in the upcoming film The Last word.
Seyfried was spotted holding onto Sadoski as they walked back to their trailers on set in Pasadena, CA on Wednesday.
The duo became friendly while working together on the off-Broadway show The Way We Get By last year, and things began to heat up when they were recently reunited on set.
When Does Amanda Seyfried Feel Most Beautiful?
Seyfried had previously dated Justin Long for over two years, before the pair split up last fall.
"They both tried very hard to make it work because they each wanted to eventually have a family but ultimately they weren't compatible and decided to split up. They are still on good terms and friends," a source told PEOPLE at the time.
Sadoski, meanwhile, split from his wife, Kimberly Hope, in October 2015 after eight years of marriage.
In The Last Word, Seyfried stars as a local writer assigned to work on the obituary of a one-time highly successful business woman, played by Shirley MacLaine.
