Up and at ‘em, Amanda Seyfried went for an early morning run around Union Square in New York City Friday (September 6). She has plenty of reasons to stay in shape, but one of them is her newly confirmed relationship with Justin Long.

The 27-year-old starlet and 35-year-old actor have been seen hanging out together regularly (along with Miss Seyfried’s dog Finn) in both New York and Los Angeles, but only recently did they decide to go public with their blossoming relationship.

Before taking up with Long, the actress previously dated her ‘Mamma Mia’ co-star Dominic Cooper for three years.

The “Les Miserables” standout recently finished her promotional tour for her most recent movie, “Lovelace,” and she’s now set her sights on playing the late musician Eva Cassidy. She said recently, “Eva has an amazing story and then she was gone. She has this whole catalogue of music--she's amazing. It's tragic.”
