Is a new romance – dare we say, puppy love – in Amanda Seyfried
The In Time
star, 26, was spotted in Los Angeles Friday morning with Dexter
's Desmond Harrington, 34.
Sporting workout duds and rival baseball caps (Detroit Tigers for him; N.Y. Yankees for her), they were accompanied by Seyfried's rescue dog, Finn.
Their hike together comes after Seyfried and Black Hawk Down
star Josh Hartnett
cooled things down earlier this summer.
Seyfried's next role – as the famous '70s adult film star Linda Lovelace in Lovelace
– will feature Seyfried sharing screen time with Sarah Jessica Parker
, Peter Sarsgaard, and James Franco
