PASADENA, Calif., March 4 (UPI) -- Amanda Seyfried and Thomas Sadoski sparked dating rumors on the set of The Last Word.
"Amanda and Thomas are definitely dating right now. She's no longer single," a source told Us Weekly magazine of the Mean Girls star.
Seyfried and Sadoski co-starred in the off-Broadway play The Way We Get By in 2015 and are said to have reconnected through The Last Word. The actress will play a journalist in the new comedy, but it is unknown if Sadoski will appear in the film.
The sighting follows Seyfried's split from boyfriend Justin Long. She and the 37-year-old actor were together two years before going their separate ways in September, reportedly because they "had different schedules and different lives."
"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," a source told People at the time. "They are still on good terms and friends."
Sadoski is known for starring in Reasons to be Pretty and The House of Blue Leaves on Broadway and played Don Keefer on HBO series The Newsroom. The actor split from wife Kimberly Hope in 2015 after eight years of marriage.
Seyfried will star in Showtime's upcoming Twin Peaks revival with Kyle MacLachlan and the Karl Rove biopic Young Americans with Daniel Radcliffe. She is also slated for Flying Horse with Benedict Cumberbatch and Ralph Fiennes.
