Seyfried, who previously dated her "Mamma Mia!" co-star Dominic Cooper, was first linked to Reese Witherspoon's ex-husband in October. They have been snapped embracing during a break on the Los Angeles set of the upcoming sci-fi film, contactmusic.com reports.

The photo, published on Usmagazine.com, shows the stars smiling and cuddling with Seyfried still in costume, donning a cropped red wig for her role opposite co-star Justin Timberlake.
